METHOD AND SYSTEM FOR PROVIDING A CHARGE PUMP FOR VERY LOW VOLTAGE APPLICATIONS

摘要

A method and system for providing an output voltage greater than a voltage provided by a voltage supply in a semiconductor device disclosed The method and system include providing a plurality of clock signals, providing a first stage and providing a second stage The first stage includes at least a first pumping node (144'), a pumping capacitor (142) and a device coupled with the pumping node (156'), and an auxiliary capacitor pan: (152/162) for providing an undershoot for the device for value(s) of the clock The auxiliary a pumping capacitors receive a first portion of the clock signals The second stage includes at least a second pumping node The first a second portions of the clock signals are provided to the first and second stages, respectively The first stage and the second stage are configured to alternately charge and fully discharge based on the clock signals
