Abstract
A rectifier circuit can include a plurality of FETs arranged as a rectifier; and a start-up circuit applied to each of the plurality of FETs that turn each of the FETs off during a circuit startup period, wherein the start-up circuit provides a large impedance for low power dissipation during normal operation of the rectifier.
