hi,

can any body explain the following question.
When the clock frequency increases power consumption also increases why?

Thanks and regards

To under this you need to look at transistor level.
Dynamic power consumption in CMOS inverter is given by P=C(V)^2F
where, P=power consumption, C=load capacitance V=operating voltage F=frequency.
CMOS Inverter Power Dissipation
Dynamic Power Consumption
