2 cards from this section. Quick, good the night before a test.
What is output impedance?
Think about how amplifiers interact with what they connect to.
Explain briefly what a cascode amplifier does.
Consider the idea of stacking transistor configurations.
What does a cascode amplifier primarily improve?
Focus on what physical addition alters the output characteristics.
True or False: A higher input impedance can lead to better signal integrity.
Think about the effect of loads attached to circuits.
Suppose you have a cascode amplifier configuration where the lower transistor has 10kΩ output impedance and the upper transistor introduces an additional 20kΩ. Calculate the total output impedance of the amplifier.
Use the parallel resistor formula to combine impedances.
Design a cascode amplifier for a given application with specific input and output requirements. What measurements would you take to ensure proper functionality?
Consider the circuit's intended application and operating range.
