ABSTRACT:
A power consumption control circuit for CMOS circuit for achieving a constant signal propagation delay time in the CMOS circuit by maintaining the same power consumption all the time. A leading edge heater and a trailing edge heater are provided in close proximity to the CMOS circuit. During a time period for a leading edge of an input pulse propagates through the CMOS circuit, the leading edge heater is turned off. During a time period for a trailing edge of the input pulse propagates through the CMOS circuit, the trailing edge heater is turned off. As result, an overall current flowing in the CMOS circuit, leading and trailing edge heaters is unchanged regardless of the repetition rate of the input pulse provided to the CMOS circuit.
