ABSTRACT:
A substrate bias generator avoids using a free-running oscillator and thereby saves power in the standby mode. A clock enable signal from a regulator sets a latch in a self-timed clock circuit. The latch setting initiates a first group of clock signals (that are used by a pump circuit for pumping), at the end of which the latch is reset but concomitantly an input circuit to the latch is disabled from recognizing a new pump signal. Resetting the latch causes the clock circuit to generate a second group of clock signals used in the charge pump to prepare fully for the next demand for pumping. At the end of the second group of clock signals, a full cycle of clocks has been completed in a self-timed manner, and the input circuit to the latch is reenabled to recognize a subsequent pump signal.
