$ Well, let's derive something close.

$ Power is given by:

$ 	P=IV

    [stuff deleted]

$ 
$ 
$ 	Pdynamic = V^2 * 2 * Pi * f * C
$ 
$ You'll see that the dynamic component of the power dissipation is

Oops ! I goofed. I've just checked closely. You are correct. P is
proportional to V^2 and NOT f^2. My apology !
