Response to the following problem:
For the PMOS differential amplifier shown in Fig. let Vtp = -0.8 V and Ω pW/L = 4 mA/V2. Neglect channel-length modulation n

a) For vG1 = vG2 =0 V, find |VOV| and VSG for each of Q1:and Q2:
Also find VS , VD1, and VD2. (b) If the current source requires a minimum voltage of 0.4 V, find the input common-mode range.
