Consider the CMOS common source amplifier circuit in Fig. 4. The transistor parameters are given as VTN = 0.5 V, VTP = −0.5 V, kn′ = 80 μA/V2, kp′ = 40 μA/V2, and λn = λp = 0.015 V −1. Assume that IBias = 0.1 mA and M2, M3 are identical. (a) Determine the small-signal parameters (gm and ro) of each transistor. (Express the transconductance gm in terms of the width-to-length ratio (W/L) without any values). (b) Draw the small-signal equivalent circuit and derive the small-signal voltage gain equation. (c) Find the width-to-length ratio of M1 such that the small-signal voltage gain is Av = −250. (d) Derive and calculate the output resistance Ro. Figure 4.
