Which of the following is the likely to experience significant changes in the values of ICQ and VCEQ as a result of changes in temperature?
A) Voltage-divider bias.
B) Emitter-feedback bias.
C) Base bias.
D) Collector-feedback bias.

Question

Quizplus · Accepted Answer

Base bias circuits are highly sensitive to variations in temperature because they lack any form of feedback to stabilize the operating point. Changes in temperature can significantly affect the base-emitter voltage and, consequently, the collector current (ICQ) and collector-emitter voltage (VCEQ). Other biasing methods, like voltage-divider, emitter-feedback, and collector-feedback bias, incorporate feedback mechanisms that help stabilize the operating point against temperature variations and transistor parameter changes.
