An IC inverter fabricated in a 0.18-μm CMOS process is found to have a load capacitance of 10 fF. If the inverter is operated from a 1.8-V power supply, find the energy needed to charge and discharge the load capacitance. If the IC chip has 2 million of these inverters operating at an average switching frequency of 1 GHz, what is the power dissipated in the chip? What is the average current drawn from the power supply?
