2 cards from this section. Quick, good the night before a test.
Describe what a cascode amplifier consists of.
Think about the stages of amplification.
What happens to the voltage gain when using a cascode configuration?
Consider how cascading affects overall gain.
What is the primary benefit of using a cascode amplifier?
Think about the configuration's effects on gain.
True or False: The output impedance of a cascode amplifier is lower than that of a single stage amplifier.
Consider what happens to impedance in cascaded circuits.
Design a cascode amplifier with an overall gain of 50 while ensuring output impedance is high. Specify the MOSFET parameters and biasing conditions to achieve this.
Consider the interplay between gain and biasing conditions.
Given a cascode amplifier configuration, calculate the maximum useful input voltage if the output impedance is known and if the next stage has a specified input impedance.
Ensure to incorporate both the voltage gains and any relevant load conditions.
