Abstract

This letter presents a pico-ampere level voltage reference with ultra-high performance of line regulation and power supply rejection ratio (PSRR) based on a self-regulation technique for Internet-of-Things (IoT) systems. Post-layout simulation results show that it achieves a minimum temperature coefficient (TC) of 18.9 ppm/oC over the temperature range from 0 oC to 120 oC with a 1.2 V supply voltage. At 27 °C, its current consumption is 98 pA. The line regulation is 0.17 ppm/V over the supply voltage range from 1.2 V to 3.0 V and the PSRR is -72 dB@100Hz.
