In Fig. 3, assume (笠)」 50 RD = 2k, VDD = 3V and λ = 0. If an output 0.5' swing from 1V to 2.5V is required, (a) Calculate input voltages that yield Vout = 1V and Vout = 2.5V. (b) Calculate the drain current and the transconductance of M₁ in both cases. (c) How much does the small-signal gain vary as the output goes from 1V to 2.5V (this variation is called the non-linearity)?
