2 cards from this section. Quick, good the night before a test.
What effect does an increase in beta have on the collector current?
Consider how beta relates to collector and base currents.
What is the main purpose of an emitter resistor in a CE amplifier?
Think about negative feedback mechanisms.
What happens to the Q-point if beta increases significantly?
Consider the relationship between beta and collector current.
True or False: A bypass capacitor allows DC signals to pass while blocking AC signals.
Think about the function of a bypass capacitor.
Given a CE amplifier with known parameters, calculate the impact on the Q-point if the temperature changes, and reevaluate the optimal design with an emitter resistor.
Use characteristic curves and stability diagrams for support.
Critique a given amplifier design for susceptibility to thermal runaway, providing modifications.
Look at both the thermal effects and the AC analysis of the amplifier.
