Abstract

A robust multioutput self-regulated rectifier without any switching circuitry is proposed in this letter for wirelessly powered biomedical devices, especially for neural stimulators. The proposed system utilizes the series and parallel resonant configuration for low- and high-side outputs, respectively, by using only one resonant capacitor. The proposed system provides dual high voltages of ±14 V for neuro stimulator and low voltage of 2.1 V for operating systems such as read-out and digital circuits.
