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

McqMate

Q.	Why is the operating frequency for CMOS devices critical for determining power dissipation?
A.	at low frequencies, at low frequencies, power dissipation increases.
B.	at high frequencies, the gate will only be able to deliver 70.7 % of rated power.
C.	at high frequencies, charging and discharging the gate capacitance will draw a heavy current from the power supply and thus increase power dissipation.
D.	at high frequencie s, the gate will only be able to deliver 70.7 % of rated power and charging and dischargin g the gate capacitanc e will draw a heavy current from the power supply and thus increase power dissipation .
Answer» C. at high frequencies, charging and discharging the gate capacitance will draw a heavy current from the power supply and thus increase power dissipation.
