摘要
基于0.18 um CMOS工艺技术,设计了一款结构简单的低温度系数的电压基准源.Spectre仿真显示,在供电电压为5V时,输出电压是1.20V;在-40℃到80℃温度范围内,温度系数可以达到3.47ppm/℃;在频率低于10KHz时,PSRR保持在54dB以下;总的输出噪声为7.304e-5V.
A low temperature coefficient and simple structure bandgap reference voltage is designed based on 0.18 μm CMOS process. The supply voltage is 5.0 V and output voltage is 1.20 V. The temperature coefficient is 3.47 ppm/℃ when temperature ranges from-40 to 85 ℃. The Power Supply Rejection Ratio always stables in 54 d B when the frequency less than 10 kHz. The total output noise is 7.304×10^（-5） V.
