Assume the Q point on a class- A amplifier is centered on the ac load line. The maximum peak- to- peak output voltage is
A)1/2 VCEQ
B)2 VCEQ
C)1/2 VCC
D)VCEQ

Question

Quizplus · Accepted Answer

When the Q point of a class-A amplifier is centered on the AC load line, the maximum peak-to-peak output voltage is twice the quiescent collector-emitter voltage (VCEQ), because the output can swing equally above and below the Q point up to the supply voltage (VCC) or down to 0V, making the maximum swing 2 VCEQ.
