Challenge Problems
Push your limits with challenges.
Question 1
Design a circuit using a NMOS with specific parameters (V_th = 2V, R_D = 100kΩ) and a V_dd of 12V. Calculate V_out for both saturation and triode regions.
💡 Hint: Graphically illustrate the load lines to validate your calculations.
Question 2
A specific NMOS has g_m = 5 mA/V and R_D = 10kΩ. Calculate the gain and predict the output if V_in varies from V_th + 1V to V_dd.
💡 Hint: Check for any potential changes in operating regions when V_in approaches V_dd.
