Challenge Problems
Push your limits with challenges.
Question 1
Design a MOSFET circuit where the goal is to sustain a current of 10mA. Given W = 20um, L = 0.5um, and Vth = 1.5V, calculate the required VGS and VDS.
💡 Hint: Use the expression for current flow under given operating conditions.
Question 2
Consider a device that is operating at the edge of pinch-off. Discuss how variations in temperature might affect the threshold voltage and, subsequently, current flow.
💡 Hint: Think about the temperature coefficients related to semiconductor behavior.
