Challenge Problems

Push your limits with challenges.

Question 1

A MOSFET has K = 3 mA/VΒ², V_th = 1.5 V, and operates with V_in = 4.5 V. Determine if it operates in saturation or triode when connected to a load of R_D = 1 kΞ©. Calculate the gain at this point.

πŸ’‘ Hint: Check the condition V_DS > V_GS - V_th to verify saturation.

Question 2

Design a MOSFET amplifier circuit needing an output current of 5 mA at a voltage gain of 10. Given K = 4 mA/VΒ², determine load resistance and the necessary input voltage to achieve the desired performance.

πŸ’‘ Hint: Use the relationships between gain, current, and resistance to find required values.
