Abstract
A high voltage clock generator including an isolation and precharge circuit to charge a bootstrap capacitance at a time prior to driving the load capacitance to a higher voltage level. The first clock generator charges a load capacitance to the initial voltage level while the isolation precharge circuit has already acted to charge the bootstrap capacitance. A second clock generator drives the bootstrap capacitance to a higher voltage level, at which time the isolation precharge circuit acts to engage the bootstrap capacitance to the load capacitance and charge the load capacitance to a higher voltage level.
