Question

Quizplus · Accepted Answer

Because a differential amplifier often uses a common emitter resistor for both transistors in its configuration, it is referred to as a "long-tail pair." This terminology highlights the characteristic of having a "long" resistor tail in the circuit, which is crucial for its differential operation.
