Abstract:

A rectifier includes a first stage to convert an AC signal to a first rectified signal and a second stage to convert the AC signal to a second rectified signal. Each stage includes a MOSFET, a differential amplifier with a predetermined gain, and an analog buffer coupled to the output of the differential amplifier. The differential amplifier generates an amplified signal based on a difference between an input signal voltage and an output signal voltage. The analog buffer outputs a gate signal to switch the MOSFET based on the amplified signal. Switching of the MOSFET converts the AC signal corresponding to the input signal voltage to a corresponding one of the first rectified signal and the second rectified signal. The first and second rectified signals may be combined to form a DC signal for driving a load.
