Thebias voltages ofthe diff-amp shown in Figure P11.35 are V+ = 5 V and V− = −5 V. The threshold voltage of each transistor is VTN = 0.4 V andv+ assume λ = 0. Let Kn3 = Kn4 = 0.20 mA/V2. The drain currents can be written as ID1 =Kn1(VGS1 − VTN)2 and ID2 = Kn2 (VGS2 = VTN)2 (a) Design the circuit such that IQ = 0.25 mA when v1 = v2 = 0. (b) If v1 =v2 = 0 and Kn1 = Kn2 = 0.120mA/V2, find vo1 − vo2 when(i)RD1 = RD2 = 15 kΩ and (ii) RD1 = 14.5 kΩ, RD2 = 15.5 kΩ. (c) Repeat part (b) for Kn1= 0.125 mA/V2 and Kn2 = 0.115 mA/V2.
