Question 1
What is the formula for calculating Ceq?
- C<sub>eq</sub> = C<sub>gd</sub> Γ |A<sub>V</sub>|
- C<sub>eq</sub> = C<sub>gd</sub>(1 + |A<sub>V</sub>|)
- C<sub>eq</sub> = C<sub>gd</sub>/(1 - |A<sub>V</sub>|)
π‘ Hint: Think about how gain interacts with capacitance.
Question 2
True or False: A higher Req increases the -3dB frequency.
- True
- False
π‘ Hint: Consider the math behind the -3dB formula.

Question 1
A MOSFET has a gate-drain capacitance (Cgd) of 4 pF and a gain of -15. Calculate Ceq and determine the -3dB frequency for Req = 1 kΞ©.
π‘ Hint: Careful with unit conversions; make sure to keep everything in consistent units.
Question 2
Given a circuit with Cgd = 10 pF, AV = 5, and Req = 200 Ξ©, verify if the determined -3dB frequency allows for audio applications.
π‘ Hint: Consider the standard frequency ranges for audio applications to evaluate performance.
