MCQ Practice Question

In a BJT amplifier, the Miller effect associated with collector-base capacitance is especially important in which configuration?

ACommon-emitter voltage amplifier
BEmitter follower with exactly unity gain
CCommon-base stage with no inversion
DDC current mirror only

Show AnswerHide AnswerReport an error

Correct Answer: A. Common-emitter voltage amplifier

Explanation: The relatively large inverting voltage gain of a common-emitter stage can multiply the effective input capacitance caused by collector-base capacitance.
