2 Question 1 (a) Assume λ = 0. Assume M1 is saturated. Given that V GS1 – V TH1 = |V GS2 – V TH2 |, what is the value of the small-signal low-frequency gain? (b) VDD M2 v out v in M1
3 Assume λ = 0, and V A =infinity. (i.e. both devices have infinite output resistance) Assume M1 is saturated. Write an expression for the low-frequency small-signal gain in terms of the small-signal transistor parameters (i.e. g m etc.) of M1 and Q2. Given that the DC difference between gate-source voltage and threshold voltage of M1 is 260mV (i.e. V BIAS1 – V TH1 ), then calculate the value of the low-frequency small-signal gain? VDD Q2 v out v in M1 V BIAS1
