Abstract
A CMOS driver or pull up circuit is provided which includes a pull up transistor of a given conductivity type and a precharged bootstrap capacitor which discharges fully through a second transistor having a conductivity type opposite to that of the pull up transistor to the control gate or electrode of the pull up transistor. A third transistor may be used to initiate discharge by providing power supply voltage to the control gate of the pull up transistor.
