For the differential amplifier in Figure P11.31 the parameters are R1 = 50 kΩ and RD = 24kΩ. The transistor parameters are: Kn = 0.25 mA/V2, λ = 0, and VTN = 2 V. (a) Determine I1,IQ, ID1, VDs1 , and VDs4 when v1 = v2 = 0. (b) Draw the dc load line and plot the Q-point for transistor M2. (c) What are the maximum and minimum values of the common-mode input voltage?
