Abstract
Described herein are circuits and methods for improving switch performance when overdriving the gate by adding a delay on a PMOS gate voltage such that it can turn on the PMOS during switch state transition to allow charge/discharge of the switch body voltage faster and it can turn off once the process is complete. For example, back-to-back diodes can be used to separate the PMOS gate and drain. This can reduce leakage current and can reduce or eliminate the potential for breakdown of the switch.
