Consider the MOSFET diff-amp shown in Figure P11.63. The bias voltages are V+ = 3 V and V− = −3 V. The current source is IQ = 200 μA and has an output resistance of Ro = 2 MΩ. The transistor parameters are VTN = 0.4 V, VTP = −0.4 VTP = −0.4 V, Kn = KP = 0.5mA/V2, λ2 = 0.02 V, V−1, λ4 = 0.03 V−1 and λ1 =λ3 = 0. (a) Determine the voltage gain A = vo/vd for v1 = vd and v2 = 0. (b) Determine the voltage gain A = vo/vd for v1 = 0 and v2 = −vd. (c) Determine the voltage gain A = vo/vd for v1 = − vd/2 and v2 = −vd/2.
