Abstract

This brief presents an ultra-low-power sub-1V voltage reference circuit using a self-cascode technique to improve power supply rejection ratio (PSRR) for battery-powered applications. The proposed voltage reference circuit has been fabricated in 22 nm fully-depleted silicon-on-insulator (FDSOI) CMOS technology, and it occupies an active area of 0.0104
