desgin a BJT amplifier that is balanced in while having a single ended output. The differential gain is 20dB= 10 V/V, and CMRR is 40dB = 100 V/V. Beta is 100 and ro = 50kohm. use dual power supplies +Vcc and -Vee.
common-mode gain Acm = 0.1 V/V, how to determine the gm and r(pi) with the given values.
