.
Note (refer to all questions): Vb, Vb1, Vb2, and Vb3 are well biased to make the M1, M2, and M3 operate in the saturation region.
Note: not only write down the equations, but also derive a couple of lines of equation (i.e., with a small signal model).
Q1. Analyze and sketch the frequency response of
CS amp.

Q4. Due to a manufacturing error, a parasitic resistance
Rp has appeared in series with the source of M1
in Fig. shown below, Assuming λ = 0 and neglecting
other capacitances, determine the input and output
poles of the circuit.
