Abstract :
The performance of many mixed analog/digital systems is limited by inaccuracies and power supply noise coupling errors in integrated voltage references. Reference circuitry also typically contributes a large fraction of the analog power consumption. The CMOS bandgap circuit described here provides a 2.0 V differential voltage reference for a 10.24 MHz oversampled data converter, and maintains high PSR and accuracy while consuming 2.2 mW.<>
