A. Choose resistor values R1 and R2so that the DC drain current value is ID1= 100 μA. Assume for this calculation thatλ effects are negligible, i. e., λ≈ 0 V−1. B. For the remaining parts of the problem, consider |λn| = |λp| = 0.01 V−1. It is desired to have the DC output voltage value VO = 5 V. Find the ratio of ID2 to IREF for this case. C. Again considering the DC output voltage value to be VO = 5 V, what is the maximum ac output voltage swing (peak-to-peak) without there occurring significant waveform clipping (i. e., the output voltage range over which Q1 and Q2 remain in saturation)?D. Construct a small-signal equivalent circuit for the amplifier that is appropriate for determining the voltage gain, vo/vi. Clearly identify relevant components and device terminals. E. Solve for the amplifier circuit’s small-signal voltage gain, vo/vi. Begin by writing an expression for the gain, and then determine its value.
