Challenge Problems
Push your limits with advanced challenges
Design a CMOS inverter circuit diagram, label NMOS, PMOS, and show input-output relation. Analyze how it reduces power consumption.
💡 Hint: Think about how only one transistor can be active at any time, minimizing current flow.
Calculate the current through an NMOS in saturation given VGS = 5V, Vth = 1V, Kn = 200uA/V^2, and VDS = 2V with channel-length modulation factor as negligible.
💡 Hint: Use the provided saturation current equation to find ID.
