Challenge Problems
Push your limits with advanced challenges
You have a MOSFET with ID = 1 mA and Vgs = 2V. Calculate gm if Vth is known to be 1V. Analyze if this improvement in gm can amplify a signal.
💡 Hint: Look for the role of Vth when calculating gm.
If a circuit containing a MOSFET has a derived small signal gain of -10 and the input voltage is 10mV, what is the output?
💡 Hint: Negative gain indicates an inversion; be careful with signs.
