Design of Negative High Voltage Generator for Biphasic Stimulator with SoC Integration Consideration

Abstract

For electronic prosthetic system-on-chip (SoC) in the commercial bulk CMOS processes, a negative high voltage generator used in a biphasic stimulator was proposed. Realized in a 0.18-mu m low-voltage CMOS process, the negative high voltage generator can deliver -8 V with a 1.8-V supply.
