A Novel High PSR Voltage Reference with Secondary Temperature Compensation

Open publisher page 9 citations

Abstract

A novel voltage reference based on Kujik [1] bandgap is proposed in this paper. An extra amplifier and bipolar are used to produce a current of positive temperature coefficient, which is for compensating the Kujik bandgap reference in high temperature. The reference finally has a temperature coefficient of only 10 ppm/_. A negative feedback loop is introduced to provide a pre-regulated power supply for the voltage reference, which has increased the power supply rejection (PSR) of the voltage reference to -120 dB@dc. The circuit has been designed with TSMC 0.35 μm CMOS process, and the measurements agree our design.
