Question 1.
Define a cascode amplifier.
Show hintHide hint
Think about the structure of how the amplifier stages are arranged.
Question 2.
What is the primary benefit of using a cascode configuration?
Show hintHide hint
Consider the motivation for cascading stages.
3Question 3.
What is the primary configuration of a cascode amplifier?
- Common source followed by common gate
- Common gate followed by common source
- Common drain followed by common source
Show hintHide hint
Think about the sequence of connections in the amplifier.
4Question 4.
True or False: The output impedance of a cascode amplifier is lower than that of a common source amplifier.
- True
- False
Show hintHide hint
Consider how cascading amplifiers influences impedance.
Question 5.
Design a cascode amplifier circuit with specified parameters for voltage gain and discuss the effects of mismatched biasing.
Show hintHide hint
Consider how transconductance impacts current flow in saturation versus triode modes.
Question 6.
Evaluate the performance of a cascode amplifier against a single-stage amplifier in terms of frequency response. Consider both bandwidth and stability.
Show hintHide hint
Reflect on how cascading stages influences both gain and bandwidth.
