Embodiments include a technique for using a charge pump for a distributed voltage passgate with high voltage protection. The technique includes receiving a reference signal, and preventing the reference signal from passing through a passgate to a circuit, wherein the passgate is an NFET passgate. The technique also includes charging the passgate using a charge pump circuit above the reference signal, and regulating the charge pump circuit using a clock signal. The technique also includes controlling the passgate based at least in part on the charge pump circuit.
