A 1.6 ppm/°C bandgap voltage reference for an extended operating temperature range

Abstract

A new CMOS bandgap voltage reference (BGR) is proposed and simulated using Silterra 0.13 µm CMOS technology. The proposed BGR utilizes 3 curvature-corrected current generators that compensate for the output voltage variation in an extended temperature range. The proposed circuit generates an output voltage of 1.181 V with a variation of 380 µV from −50 °C to 150 °C.
