Challenge Problems
Push your limits with advanced challenges
A MOSFET circuit is designed with a set operating point that provides a gain of 10. If the biasing voltage changes, describe how this affects transconductance and the output gain.
💡 Hint: Consider what happens to the parameters when the operating point shifts.
How would you redesign a small signal model for a circuit operating at frequencies above 1MHz?
💡 Hint: What additional components do high frequency circuits generally include?
