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/).

基于CMOS/SIMOX /spl Sigma/-V/sub - TH/架构的0.6 v电压基准电路

提出了一种基于阈值-电压求和(/spl Sigma/-V/sub - TH/)结构的基准电压电路。其输出(V/sub REF/)不受电路中反馈放大器输入偏置的影响。因此，它的V/sub REF/色散大大降低。采用完全耗尽CMOS/SIMOX技术制作的原型电路可以在低至0.6 V的电源电压下工作。测得的V/sub REF/为530 mV/spl plusmn/16.8 mV(30)，测得的温度系数为0.02 mV//spl°/C/spl plusmn/0.0G mV//spl°/C (3/spl sigma/)。
