All MOS transistors bandgap reference using chopper stabilization technique

Abstract

A 0.6-V, 8-μW bandgap reference without BJTs is realized in the standard CMOS 0.13μm technology. All MOS transistors bandgap reference circuit with very low supply voltage 0.6V is designed. The chopper stabilization technique is used to improve the accuracy of the bandgap reference voltage. The measurement results have confirmed that the chopper stabilization technique reduces bandgap voltage error from 100mV to 30mV comparing to the one without chopper stabilization technique.
