Problem 4. Common-source

(Raxavi: 3.4) In Fig. 3, assume (),

swing from 1V to 2.5V is required,

(a) Calculate input voltages that yield V-1V and Vot-2.5V.

(b) Calculate the drain current and the transconductance of M₁ in both cases.

(e) How much does the small-signal gain vary as the output goes from 1V to 2.5V (this

variation is called the non-linearity)?
