ABSTRACT:
A circuit arrangement includes a charge pumping circuit (25) and a signal-transition-detection circuit (27). The charge pumping circuit is responsive to high and low level logic signals, for alternately storing charge in a pumping capacitor (34) and transferring the stored charge from the pumping capacitor to a load (22). The signal-transition-detection circuit is responsive to both negative-going and positive-going input signal transitions (RL1) for producing and applying to the charge pumping circuit full-cycle logic signals (VPPTD). Plural signal-transition-detection circuits (27 and 57) can be used in tandem to increase benefits to the circuit arrangement.
