Differential Amplifiers

Dual Input Unbalanced Output Differential Amplifier: It is an important configuration and converts dual inputs into a single ended output. In this configuration, two input signals are applied and the output is measured at only one of the two collectors (either at C1 or at C2) with respect to ground. The output is called the […]

Dual Input Balanced Output Differential Amplifier: The dual input balanced output differential amplifier configu­ration is shown in Fig. 20.2. In the given circuit two input signals vin1 and vin2 are applied to the bases B1 and B2 of transistors Q1 and Q2. The differential input under amplification is the differ­ence of the two input signals vin1
