Abstract :
A curvature-corrected bandgap reference that can function at supply voltages as low as 1 V, at a supply current of only 100 μA, is presented. After trimming, this bandgap reference has a temperature coefficient (TC) of ±4 p.p.m./°C. The reference voltage is about 200 mV and it can easily be adjusted to higher values. The temperature range of this circuit is from 0 to 125°C. This bandgap reference is realized using a standard bipolar process with base-diffused resistors
