2 cards from this section. Quick, good the night before a test.
What does input resistance represent in an amplifier circuit?
Think about how signals interact when they first enter the circuit.
Define the Miller effect.
Consider how feedback mechanisms affect input characteristics.
What is the input resistance of an amplifier?
Think about the point where signals are first connected into the circuit.
True or False: Voltage gain is always negative in a common emitter amplifier.
Consider the amplifier's behavior with respect to input and output signals.
Design a CE amplifier with R_in of 2 kΩ and R_out of 4 kΩ. Determine mid-frequency gain given a load capacitance of 200 pF.
Use the relationships taught in class for gain computation.
You're tasked to redesign a common source amplifier aiming to improve upper cutoff frequency. What component changes would you consider?
Recall the influence of capacitance and resistive loads on frequency response.
