-Change the peak amplitude of the AC input waveform. What is the minimum peak value of the AC input where the PMOS transistor is still actively rectifying the input, i.e. the V<sub>GS</sub> is greater than the threshold voltage and the device is turned on? What determines this minimum voltage?+Change the peak-to-peak amplitude of the AC input waveform.
