Abstract:
An apparatus comprising:a switching device to transfer charge from its input terminal to its output terminal upon activation of said switching device, wherein said input terminal is an input for said apparatus and said output terminal is an output for said apparatus, said switching device further comprising a substrate terminal coupled to said input terminal; a pull-up device coupled to said switching device, said pull-up device to precharge a boot node, coupled to a control terminal of said switching device, when said pull-up device is turned on, said pull-up device further comprising a substrate terminal couple to said input terminal of said switching device; a pull-down device coupled to said switching device, said pull-down device to discharge said boot node when a gate of said pull-down device is turned on, said pull-down device further comprising a substrate terminal coupled to said input terminal of said switching device; a boot capacitor coupled to said boot node, said boot capacitor to hold a first charge on said boot node when a voltage potential on said boot node is boosted with a first clock signal; a control device coupled to said pull-down device, said control device activated with a second clock signal to enable and disable said pull-down device by turning on and off said pull-down device, said control device further comprising a substrate terminal coupled to a drain terminal of said control device; and a storage capacitor coupled to said output terminal of said switching device, said storage capacitor to hold a second charge at a pump node, wherein said second charge is boosted with said second clock signal.
