Consider the basic differential circuit in which the transistors have β = 100 and VA =100 V, with I = 0.2 mA, REE =500 kΩ, and RC =25 kΩ. The collector resistances are matched to within 1%. Find:
(a) the differential gain
(b) the differential input resistance
(c) the common-mode gain
(d) the common-mode rejection ratio
(e) the common-mode input resistance
