Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given a MOSFET with Cgs = 150 pF, Cgd = 50 pF, and a gain of 10, calculate the effective input capacitance considering the Miller Effect. How does it affect the bandwidth?

💡 Hint: Remember to apply the Miller formula directly for inputs.

Challenge 2 Hard

Design a scenario where the total capacitance (Cgs + Cgd) significantly impacts the FET performance at higher frequencies. Discuss how the designer could mitigate this.

💡 Hint: Focus on capacitance components collectively affecting frequency behaviors.
