This paper presents a voltage reference (VR) with low temperature coefficient (TC) and full frequency high power supply rejection ratio (PSRR), the VR is fabricated by 0.18 μm CMOS process. The proposed VR uses different methods to compensate for the temperature curvature of the output voltage twice. Two different methods are used to compensate PSRR in high-frequency band and low-frequency band respectively by analyzing the performance of PSRR in different frequency bands. Measurement data of samples show the TC of the proposed VR reaches 1.5 ppm/° C within temperature range from −40 °C to 120 °C, PSRR reaches −77.7 dB at 100 Hz and −47.7 dB at 1 MHz. The line sensitivity (LS) is 0.05%/V.

本文提出了一种参考电压（VR）与低温度系数（TC）和全频率高的电源抑制比（PSRR）时，VR是由0.18制备 μ中号的CMOS工艺。拟议的VR使用不同的方法两次补偿输出电压的温度曲率。通过分析不同频段的PSRR性能，分别采用两种不同的方法补偿高频段和低频段的PSRR。样品的测量数据表明，拟议的VR的TC在−40°C至120°C的温度范围内达到1.5 ppm /°C，PSRR在100 Hz时达到−77.7 dB，在1 MHz时达到−47.7 dB。线路灵敏度（LS）为0.05 ％ / V。
