Abstract
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 muA. After trimming this bandgap reference has a temperature coefficient (TC) of +/- 4 ppm/degrees-C. The reference voltage is abou t 200 mV and it can simply be adjusted to higher reference voltages. T he temperature range of this circuit is from 0 to 125-degrees-C. This bandgap reference is realized using a standard bipolar process with ba se-diffused resistors.
