| Construct the circuit as shown in figure 2 on your solder-less breadboard. The green boxes indicate connections to the ADALM2000. Starting with the circuit from experiment 1, remove one of the 20K? resistors (old R<sub>3</sub>) and replace capacitor C<sub>1</sub> with a 1K? resistor (new R<sub>3</sub>). Add diode D<sub>1</sub> and resistor R<sub>5</sub> as shown to the base of M<sub>2</sub>. Be sure to replace C<sub>2</sub> with the original 47 uF capacitor. | Construct the circuit as shown in figure 4 on your solder-less breadboard. The green boxes indicate connections to the ADALM2000.
