Challenge Problems
Push your limits with advanced challenges
Design a CMOS inverter that can operate efficiently with a power supply of 3.3V and withstand a load capacitance of 10pF. Discuss your transistor sizing and how this influences power and speed.
💡 Hint: Consider the trade-offs with increased transistor sizes versus power consumption.
Given a switching frequency of 1 GHz and capacitance of 20pF, calculate the dynamic power consumption of the CMOS inverter. How does this compare to its static consumption in typical usage?
💡 Hint: Recall the formula and consider static contribution as minimal if inactive.
