A single BJT differential pair is shown below. For RL1 and RL2 =1 k , calculate IBIAS to set VO1 and VO2 at a level that will give the maximum output swing. Assume VCEsat =0.2 V and VBE = 0.7 V. With your value of IBIAS calculate the differential mode gain Adm = vout/vin and the common mode gain Acm=vout/vin. What is the CMRR? FIGURE 1.

Differential BJT amplifier 1. Introduction The differential amplifier has two input signal sources. The ideal differential amplifier produces an output voltage that is the difference between the two input voltages.

The differential amplifier can be implemented with BJTs or MOSFETs. A differential amplifier multiplies the voltage difference between two inputs (Vin+ - Vin-) by some constant factor Ad, the differential gain. It may have either one output or a pair of outputs where the signal of interest is the voltage difference between the two outputs.
