Question

Why is the operating frequency for CMOS devices critical for determining power dissipation?

Accepted Answer

at high frequencies, charging and discharging the gate capacitance will draw a heavy current from the power supply and thus increase power dissipation.

Answer

at low frequencies, at low frequencies, power dissipation increases.

Answer

at high frequencies, the gate will only be able to deliver 70.7 % of rated power.
