Abstract

Bandgap Voltage reference (BGR) are crucial components in analog circuits. This paper introduces a BGR circuit designed in the subthreshold region using Cadence Generic Process Design Kits (GPDK) 90 nm technology. The cascoding technique is used to remove channel length modulation effect to get stable output voltage for a wider range of temperature and supply voltage. The proposed circuit produces a reference voltage of 344 mV, consuming 94.64 nW power at room temperature with a supply voltage starting from 550 mV. The temperature coefficient is measured to be 8.337 ppm/^OC within a temperature range of −45 ^OC to 170 ^OC with a line regulation of 0.017 %/V. The designed BGR circuit can be used in analog applications.
