Solve the following:
Q: Figure shows an amplifier utilizing a current mirrorQ2: Q3: Here Q1:is a common-source amplifier fed with Vi = VGS +vi , where VGS is the gate-to-source dc bias voltage of Q1: and vi is a small signal to be amplified. Find the signal component of the output voltage vO and hence the small-signal voltage gain vo/vi . Also, find the small-signal resistance of the diode-connected transistor Q2: in terms of gm2, and hence the total resistance between the drain of Q1: and ground. What is the voltage gain of the S amplifier Q1: Neglect all ro's
