Abstract
A voltage reference circuit based on threshold-voltage-summation (/spl Sigma/-V/sub TH/) architecture is proposed. Its output (V/sub REF/) is not affected by the input offset of the feedback amplifier in the circuit. Thus, its V/sub REF/ dispersion is considerably reduced. A prototype circuit fabricated in fully depleted CMOS/SIMOX technology can operate at a supply voltage as low as 0.6 V. The measured V/sub REF/ is 530 mV/spl plusmn/16.8 mV (30) and the measured temperature coefficient is 0.02 mV//spl deg/C/spl plusmn/0.0G mV//spl deg/C (3/spl sigma/).
