Abstract

A control method for a clock signal for a CPU contained in a CMOS circuit includes: when a load current for the CMOS circuit is enabled, generating a first clock signal; in a first period, selectively gating certain cycles of the first clock signal to generate a second clock signal which has a clock rate less than a clock rate of the first clock signal; and in a second period, dithering in the gated cycles to increase the clock rate of the second clock signal to be equal to that of the first clock signal. The second clock signal is continuously input to the CMOS circuit during the first period and the second period.
