Abstract: A high voltage NMOS switch is adjustable in order to optimize the switch for proper operation with different circuit configurations. A high voltage booster, included within the high voltage NMOS switch, enables the switch to reclaim the previously unused second half-cycle of a power source waveform signal, which thereby increases the speed of the NMOS switch by a factor of two. In addition, the high voltage NMOS switch provides added ramp rate flexibility by enabling a user to optimize the ramp rate of the high voltage NMOS switch for different circuit configurations.
