What is a cascode amplifier?
Think about the arrangement of transistors.
What does transconductance measure?
It's related to the input-output voltage relationship.
What is the primary benefit of a cascode amplifier?
Consider what is specifically improved in this amplifier type.
True or False: Increasing output resistance of a cascode amplifier generally leads to higher bandwidth.
Reflect on the trade-offs discussed earlier.
A cascode amplifier shows a gain of 50, but the input capacitance is causing concern. If the output stage resistance is increased, predict the impact on bandwidth and justify.
Use the relationship between capacitance and frequency response.
Design a cascode amplifier with a target gain of 200 and analyze how varying the input resistance affects overall performance.
Exploit the gain relationship while keeping resistance in mind for your calculations.
