A class C amplifier is being designed to accept a +5 Vpk input. What biasing voltage should be applied to the base of the transistor?
A) -5 V
B) -4 V
C) -3 V
D) +4 V

Question

Quizplus · Accepted Answer

Class C amplifiers are biased so that the transistor conducts for less than 180° of the input signal. To achieve this with a +5 Vpk input, the biasing voltage should be negative but less than the peak input voltage, making -4 V the correct choice to ensure the transistor remains off for more than half of the input cycle.
