Emitter-degenerated differential amplifiers shown

Reference no: EM131037369

For each of the emitter-degenerated differential amplifiers shown in Fig. P9.47, find the differential half-circuit and derive expressions for the differential gain Ad and differential input resistance Rid . For each circuit, what dc voltage appears across the bias current source(s) in the quiescent state (i.e., with vid = 0)? Hence, which of the two circuits will allow a larger negative VCM?
