4 cards from this section. Quick, good the night before a test.
What is the small signal model used for?
Think about AC signals and their effects on DC circuits.
Name the two parasitic capacitances in BJTs.
Consider the connections of the transistor terminals.
What does the small signal model assume about DC signals?
Consider the implications of 'small signal' analysis.
True or False: Parasitic capacitances have no effect at low frequencies.
How do capacitances influence frequencies?
Design a Common Emitter amplifier circuit that includes measures to handle potential thermal runaway issues. Discuss what elements will enhance stability.
Think about how feedback works in stabilizing circuits.
If a BJT has an Early voltage of 100V and a collector-emitter voltage of 10V, calculate how the output current might change when the voltage increases to 20V.
Refer to the changes in collector current with respect to V_ce variations.
