Electronic Devices & Circuits BJT Biasing

For symmetrical maximum undistorted voltage swing in a simple class-A common-emitter stage, the Q-point is commonly chosen near?

ACutoff only
BSaturation only
CThe middle of the DC load line
DZero collector current and zero VCE simultaneously

Show AnswerHide AnswerReport an error

Correct Answer: C. The middle of the DC load line

Explanation: Biasing near the center of the DC load line allows approximately equal signal swing toward cutoff and saturation.
