Bipolar differential amplifier with emitter degeneration

Reference no: EM131037374

A bipolar differential amplifier with emitter degeneration resistances Re and Re is fed with the arrangement shown in Fig. P9.50. Derive an expression for the overall differential voltage gain Gv ≡ vod /vsig. If Rsig is of such a value that vid = 0.5vsig, find the gain Gv in terms of RC, re, Re, and α. Now if β is doubled, by what factor does Gv increase?
