4 cards from this section. Quick, good the night before a test.
What is the role of a current mirror in an amplifier circuit?
Think about mirroring.
Define the term 'biasing' in the context of transistor circuits.
It's about preparing the operating point.
What is the primary function of a current mirror?
Consider its name and think about the action it performs.
Biasing a transistor ensures it operates in which region?
Think of biasing as setting the stage.
Design a common emitter amplifier with a specified output voltage gain of 1000 and determine the necessary current mirror configuration to achieve this gain.
Consider voltage gain formulas and transistor role definitions.
Investigate the impact of a β mismatch (varying device β values) on the current mirror's performance. How would you modify the circuit to maintain stable output?
Look into how feedback can stabilize outputs.
