Problem 4: (a) What are the Q-points for the transistors in the amplifier in Fig. P15.24 if VDD = 15 V, VSS = 15 V, RSS = 62 kΩ, and RD = 62 kΩ? Assume Kn = 400 μA/V2 and VTN = 1 V. (b) What are the differential-mode gain, common-mode gain, CMRR, and differential-mode and common-mode input resistances? Figure P15.24
