摘要
基于负反馈技术，提出了一种超低功耗、低电源电压和高电源抑制比(PSRR)的互补金属氧化物半导体(CMOS)基准电压，并采用0.18标准微米CMOS技术进行了仿真。工作电压范围:0.85 V ~ 2.5 V，工作温度范围:-20℃~ 80℃。该基准电压可实现16.3 ppm/°C的温度系数和低至0.086 ppm/V的线路灵敏度，无需使用电阻或特殊器件，在27°C下消耗202na电流。此外，PSRR在1hz时仅为-113 dB，在1khz时为-64 dB。
Ultra-low-power, high PSRR CMOS voltage reference with negative feedback
Based on negative feedback technique, a complementary metal-oxide semiconductor (CMOS) voltage reference with ultra-low-power, low supply voltage and high-power supply rejection ratio (PSRR) is proposed and simulated using a 0.18 standard micrometre CMOS technology. The operating supply voltage ranges from 0.85 V to 2.5 V and the temperature ranges from -20°C to 80°C. The voltage reference can achieve a temperature coefficient of 16.3 ppm/°C and line sensitivity as low as 0.086 ppm/V, without the use of resistors or special devices, consuming 202 nA current at 27°C. Besides, the PSRR is only -113 dB at 1 Hz, -64 dB at 1 kHz, respectively.
