How differential amplifiers can be configured and what are they?
Answer: A differential amplifier consists of two transistors. Depending on the way of connecting the input to them and depending on the way of measuring output, there are four configurations of differential amplifier, they are:
- Dual input balanced output differential amplifier.
- Dual input unbalanced output differential amplifier.
- Single input balanced output differential amplifier.
- Single input unbalanced output differential amplifier.
