Abstract:
A circuit comprising:a charge pumping circuit, responsive to a signal having high and low levels on a lead, for alternately storing charge in a pumping capacitor and transferring the stored charge from the pumping capacitor to a load;a terminal for receiving an input signal having negative-going and positive-going transitions;a first signal-transition-detection circuit, responsive to the negative-going input signal transitions on the terminal, for producing and applying to the lead of the charge pumping circuit a full-cycle signal having high and low levels for each negative-going input signal transition; andthe first signal-transition-detection circuit, further responsive to the positive-going input signal transitions on the terminal, for producing and applying to the lead of the charge pumping circuit a full-cycle signal having high and low levels for each positive-going input signal transition.
