Assume all MOSFETs in the three circuits below are in the saturation region, ignore body effect and assume >=0. a) Calculate the small-signal voltage gain of each circuit in terms of gm and ro (30pt). b) Estimate the output resistance for each circuit. (30pt) c) Assume the supply VDD has some noise (for example ripple). For circuits b) and c only find the small signal gain from the supply to Vout (hint: you need to short Vin to ground). (20pt) d) For circuits b) and c only suggest a biasing scheme assuming you have only one ideal current source.
