摘要

An Offset Canceled Bandgap Reference (BGREF) circuit is reported in TSMCs 28nm technology node. This BGREF has a 3-sigma untrimmed inaccuracy of +/- 0.534% with a power consumption of 58uW and an estimated area of 2142um(2) which is one of the smallest BGREFs reported. The BGREF uses a closed loop circuit with a Folded Cascode Amplifier.
