CHARGE PUMP FOR DISTRIBUTED VOLTAGE PASSGATE WITH HIGH VOLTAGE PROTECTION
First Claim
1. A method for using a charge pump for a distributed voltage passgate with high voltage protection, the method comprising:
- receiving a reference signal;
preventing the reference signal from passing through a passgate to a circuit, wherein the passgate is an n-channel field-effect transistor (NFET) passgate;
charging the passgate using a charge pump circuit above the reference signal;
regulating the charge pump circuit using a clock signal; and
controlling the passgate based at least in part on the charge pump circuit.
