===== Overview =====
The easy to use [[adi>ADALM2000]] active learning module (M2K) helps introduce electrical engineering students and hobbyists to the fundamentals of signals and systems. Designed for students at all levels and from all backgrounds, the module can be used for both instructor-led and self-directed learning to help students develop a foundation in exploring signals and systems into the tens of MHz that they can build on as they pursue science, technology, or engineering degrees, without the cost and bulk associated with traditional lab gear.

With 12-bit ADCs(running at 100MSPS) and DACs(at 150MSPS), the ADALM2000 brings the power of high performance lab equipment to the palm of your hand. When coupled with Analog Devices' Scopy graphical application software running on a computer, provides the user with the following high performance instrumentation:\\

  * Two-channel oscilloscope with differential inputs
  * Two-channel arbitrary waveform generator (AWG)
  * 16-channel digital logic analyzer (3.3V CMOS and 1.8V or 5V tolerant, 100MS/s)
  * 16-channel pattern generator (3.3V CMOS, 100MS/s)
  * 16-channel virtual digital I/O
  * Two input/output digital trigger signals for linking multiple instruments (3.3V CMOS)
  * Two-channel voltmeter (AC, DC, ±25V)
  * Network analyzer – Bode, Nyquist, Nichols transfer diagrams of a circuit. Range: 1Hz to 10MHz
  * Spectrum Analyzer – power spectrum and spectral measurements (noise floor, SFDR, SNR, THD, etc.)
  * Digital Bus Analyzers (SPI, I²C, UART, Parallel)
  * Two programmable power supplies (0…+5V , 0…-5V)
Small enough to fit in a shirt pocket, the M2K is completely self-contained and entirely USB powered with the default firmware. Because M2K is enabled by libiio drivers, it supports OS X® , Windows®, and Linux®, which allows students to learn and explore on a variety of host platforms. In addition, the cross-platform [[university:tools:m2k:libm2k:libm2k|libm2k]] interface library allows users to communicate with the M2K their own C, C#, or Python programs.

===== Analog Inputs =====
====Input Dividers and Gain Control====
The gain mode is selected in this stage by the SoC, enabling the corresponding switch from ADG612 device.
ADG612 is  a monolithic CMOS device containing four independently selectable switches with the characteristics:
  * Ultralow charge injection (1 pC typically)
  * Dual ±2.7 V to ±5.5 V or single +2.7 V to +5.5 V operation
  * Automotive temperature range: −40°C to +125°C
  * Small, 16-lead TSSOP and SOIC packages 
The ADALM2000 hardware design includes two gain range settings for the analog input voltage divider:

  * High gain mode: for signals from -2.5 V to +2.5V 
  * Low gain mode: for signals from -25 V to 25 V 
A logic high on EN_SC1_HG turns switch 1 and switch 3 on, selecting high gain mode (gain of <m>HG_1</m>).\\
A logic high on EN_SC1_LG turns switch 2 and switch 4 on, selecting low gain mode (gain of <m>LG_1</m>).\\
Where:\\
<m>HG_1=(R_20 + R_21)/(R_19+R_20+R_21) = (200 K +21 K)/(820K +200K +21K)=0.212</m>\\
<m>LG_1=( R_21)/(R_19+R_20+R_21) = (21 K)/(820K +200K +21K)=0.020</m>\\

==== Buffers ====
After the input divider stage in the signal chain is the buffer stage. A dual AD8066 FET input Op Amp is configured as a unity-gain buffer that presents a high-impedance to the dividers' outputs and drives the following stage. R-C compensation networks in the figure help to maximize the bandwidth and reduce peaking (especially at unity gain).
<WRAP centeralign>{{:university:tools:m2k:users:m2k_sc_buffer.png?500|}}</WRAP>
<WRAP centeralign> Figure 6. Buffer stage </WRAP>

The useful features of the AD8066 are:
  * FET input amplifier
  * 1 pA input bias current
  * Low cost
  * High speed: 145 MHz, −3 dB bandwidth (G = +1)
  * 180 V/μs slew rate (G = +2)
  * Low noise 7 nV/√Hz (f = 10 kHz), 0.6 fA/√Hz (f = 10 kHz)
  * Wide supply voltage range: 5 V to 24 V
  * Rail-to-rail output
  * Maximum offset voltage of 1.5 mV
  * Excellent distortion specifications
  * SFDR −88 dBc @ 1 MHz
  * Low power: 6.4 mA/amplifier typical supply current
  * Small packaging: MSOP-8
 
====ADC Drivers====
The ADC driver consists of a ADA4940 for each analog input channel. This fully differential ADC driver is a low noise, low distortion device, with very low power consumption.
Along with the passive components, this stage gives gain factor equal to 1.3 for the differential signal that comes from the previous buffer stage and a gain factor equal to 1 for the offset and reference signals.

Another ADA4940 and 2 Schottky diodes are used to provide protection to the ADC inputs of each channel against voltage levels above the absolute maximum ratings. In the datasheet of AD9963 the full scale input range of the ADC is 1.56Vpp differential with an absolute maximum rating from -0.3V to 2.1V so the protection circuit will clamp voltages around these values.


{{ :university:tools:m2k:users:adc_driver.png?600 |}}
<WRAP centeralign> Figure 7. ADC Driver </WRAP>

====References and offset=====
Reference and offset voltages are implemented with an AD8567, a dual, micropower, precision, rail-to-rail input/output amplifier optimized for high output current capability and large capacitive loads.
Other features of this operational amplifier are:
  * low offset voltage (max 350 uV)
  * low input bias current (max 20pA)
  * GBW : 230 kHz at Av=100
  * Unity-gain crossover: 320 kHz
  * Single-supply operation: 2.7V to 18V
  * Dual-supply operation: ±1.35 V to ±9 V
The reference stage has a 1.2V reference input signal. The reference signal is amplified with a gain equal to 1.333 before it reaches the ADC driver.
{{ :university:tools:m2k:users:scope_reference.png?600 |}}
<WRAP centeralign>Figure 8. Reference Amplifier </WRAP>
In the offset stage, the input signal is generated by AD5625 12-bit nanoDAC. This signal is amplified with 2.693 before it reaches ADC driver.
{{ :university:tools:m2k:users:scope_offset.png?600 |}}
<WRAP centeralign> Figure 9. Offset Amplifier</WRAP>
The reference and offset voltages are derived from an AD5625 nanoDAC, which uses a 2-wire I2-compatible serial interface.It has single supply operation(from 2.7V to 5.5V) and is guaranteed monotonic by design.

===== Waveform Generator =====
====I/V====
The AD9963 DACs are a current steering architecture, so it is necessary to convert the TXIP,TXIN,TXQP,TXQN outputs to a voltage for the AWG frontend. This operation is performed by an AD8058 dual voltage feedback amplifier.
The output currents from the TXIP and TXIN pins are complementary, meaning that the sum of the two currents always equals the full-scale current of the DAC. The digital input code to the DAC determines the effective differential current delivered to the load. TXIP provides maximum output current when all bits are high. The output currents vs. DACCODE for the DAC outputs are expressed as <m> I_TXIP=[DACCODE/2^N]*I_OUTFS      </m>\\
where<m> DACCODE = 0 to 2^N-1. </m>
The DAC full-scale output current is regulated by the reference control amplifier and is determined by the product of a reference current, a programmable reference resistor, an internal programmable resistor, and a pair of programmable gain scaling parameters. There are a number of adjustments that can be made to scale IOUTFS
to provide programmability in the output signal level.  
There are 2 available ranges for the DAC full scale current: 4 mA full scale or 1 mA full scale. This current is converted by the AD8058 into voltage for the last stages of the AWG front end.
\\
{{ :university:tools:m2k:users:curent.voltage_awg.png?600 |}}
<WRAP centeralign>Figure 11. Current to voltage converter </WRAP>

The AD8058 has a very low input bias current value (typically 0.5 µA) and is and is configured as a current to voltage converter such that:\\
<m>V_+=V_-</m>\\
<m>V_-=V_out+(I_(DAC-AWG1N) * R_95)</m>\\
<m>V_+=(I_(DAC-AWG1P)* R_93)</m>\\
<m>V_out=I_(DAC-AWG1P)* R_93 - I_(DAC-AWG1N) * R_95</m>\\
The output voltage range of the AD8050  will be different, depending on the DAC full scale output current:
|Input current (AD8058)|Output Voltage (AD8058)|
|4 mA FS| -0.496 V -> 0.496 V|
|1 mA FS| -0.124 V-> 0.125 V |



====Output stages====
The AWG reference is generated with ADR3412 high accuracy voltage reference. The 1.2 V signal is then passed through a buffer implemented with AD8657.

=====Clock and Oscillator=====
The ADF4360-9 is the clock generator used in ADALM2000, with a 20MHz reference generated by a precision oscillator(Y1). This integrated integer-N synthesizer and voltage controlled oscillator (VCO) allows a frequency range of between 65 MHz to 400 MHz.
The ADF4360-9 is programmed through a 3-wire interface, the power supply range is 3.0 V to 3.6 V, and a low-power shutdown mode reduces supply current to 7μA.

===== Digital IO =====

<WRAP centeralign>{{ :university:tools:m2k:users:digitaliopins.png?1000 |}}</WRAP>

<WRAP centeralign>Figure 15. Digital I/O</WRAP>

Digital IO connections to P1 are shown in the figure above. 
P1 is the end user signal connector, with 30  pins corresponding to the input analog channels, the user power supplies, the signal generator channels, 4 GND pins and digital IO pins.
The Digital IO interface includes 18 pins, 16 of which are the Digital IO channels and the other two are trigger pins.
IO pins are LVCMOS3V3 compatible and have ESD protection for large currents provided by Schottky Diodes (D11-D19).
Short circuit protection is provided by the PRG18BB221MB1RB PTC protection devices on the digital lines (RT10-18). These components provide fault protection at the expense of limiting the bandwidth of the digital pins slightly when configured as inputs. Similarly, in digital output mode, the 200Ω resistance and the capacitance of the circuit being driven will limit bandwidth.
<WRAP todo>input bandwidth calculation based on 200Ω and 4.4pF + Zynq Cin</WRAP>

<WRAP alert>
**Note:**
When connecting the digital pins to any external device and the ADALM2000 is powered off, the ESD protection diodes on the ADALM2000 will turn on, pulling any signals to ground. Any high logic level of the external signal will be reduced to ~ 0.6V.

<WRAP todo>Would be good to describe a practical series resistance to safely sniff 5V logic, considering the unpowered case where the internal 3.3V supply could potentially be "dragged" higher than 3.3V </WRAP>

===== Power Supplies =====
====User power supplies====
The user power supplies are implemented with two ADA4805 amplifiers, one in noninverting configuration for the positive power supply and the other in inverting configuration for the negative power supply.
These amplifiers are rail-to-rail output, with ultralow pupply current (500µA per amplifier) and with a typical 0.2 µV/°C offset drift. A shutdown pin allows dynamic management of the amplifier's supply current. The outputs are guaranteed to source and sink 58mA, making them suitable for use as an adjustable positive or negative power supply with a maximum specified load current of 50mA. Compensation networks allow the amplifier to drive a 1μF output capacitance, providing a low AC output impedance to the load.

{{ :university:tools:m2k:users:user_powersupplies.png?600 |}}
<WRAP centeralign>Figure 16. User power supplies</WRAP>
The ADA4805 shutdown pin is controlled by the SoC through a p-Channel MOSFET. The device will turn of if the pin is pulled to a voltage with more than 1V below midsupply.

{{ :university:tools:m2k:users:enable_supplies.png?300 |}}  
<WRAP centeralign>Figure 17. Enable supplies</WRAP>

Control signals for the supplies are generated by an AD5627 dual 12 bit nanoDAC, with an output range of 0-1V corresponding to a range of 0 to 5.02V for the positive supply and 0 to -5.1V for the negative supply.

{{ :university:tools:m2k:users:ad5627.png?500 |}}
<WRAP centeralign>Figure 18. AD5627 nanoDAC</WRAP>

The amplifier used for the positive user power supply has a gain of 5.02:\\
<m>gain_pos=1+(R_161/R_158)=1+((4.02k)/(1k))=5.02</m>\\
For the negative user supply amplifier the gain is -5.1:\\
<m>gain_neg=-(R_160/R_159)=-((5.1k)/(1k))=-5.1</m>\\

The outputs of the ADA4805s (SUPPLY_POS and SUPPLY_NEG) correspond to the V+ and V- pins on the user connector. Output voltages are also monitored through scaling circuits with a gains of 1/2 and -1/2 that are then connected to the AD9963's AUXIO pins. The monitoring function is useful for detecting supply overcurrent and / or short circuits in the circuit being powered.
{{ :university:tools:m2k:users:supply_monitor.png?600 |}}
<WRAP centeralign>Figure 19. User supply signals division</WRAP>

The positive supply monitoring signal is obtained with a resistive divider with a gain of 1/2 and the negative supply monitor signal is obtained with an inverting amplifier with gain -1/2:\\
<m>G=-(R_136/R_139)=-((2k)/(4.02k))=-1/2</m>
