In low-power-dissipation CMOS circuitry, conventional CMOS inverters are powered by a repetitively ramped power supply. Clock signals are needed in the circuitry for controlling data flow therein. To ensure optimal low-power operation of the circuitry, clock signals are derived directly from the ramped power supply waveform itself. Additionally, a technique similar to that employed in the clock-si...
