Challenge Problems
Push your limits with advanced challenges
Given a MOSFET with Vgs = 2V, and a drain current of 1mA, calculate the small signal transconductance g_m if Vth = 1V.
💡 Hint: Use the transconductance formula directly related to Vgs and Vth.
Analyze how adding a capacitance in parallel with the MOSFET's source would affect the small signal analysis in a high-frequency circuit.
💡 Hint: Think about how capacitance impacts current flow at higher frequencies.
