Response to the following question:
A source follower for which k1n = 200 μA/V2, V1A =20 V/μm, χ = 0.2, L = 0.5 μm, W = 20 μm, and Vt = 0.6 V is required to provide a dc level shift (between input and output of 0.9 V.) What must the bias current be? Find gm, gmb, ro, Avo , and Ro. Assume that the bias current source has an output resistance equal to ro. Also find the voltage gain when a load resistance of 2 kΩ is connected to the output.
