A Low Power Bandgap Voltage Reference with Nonlinear Voltage Curvature Compensation

A Curvature-Corrected Low-Voltage Bandgap Reference

A new curvature-corrected bandgap reference is presented which is able to function at supply voltages as low as 1 V, at a supply current of only 100 PA. After trimming this bandgap reference has a temperature coefficient (TC) of +4 ppm/OC. The reference voltage is about 200 mV and it can simply be adjusted to higher reference voltages, The temperature range of this circuit is from O to 125” C. ...

Low Voltage, Low Power CMOS Bandgap References

A new curvature-corrected CMOS bandgap voltage reference

The current paper presents an improved bandgap voltage reference (BGR) that utilizes curvature-corrected current generators which compensate for the voltage reference at lower and higher temperature range. The voltage reference is operated with a supply voltage of 2.5V to achieve an output reference of 1.1835V. The temperature coefficient achieved from the circuit is 1.342 ppm/◦C, resulting fro...
