摘要 在经典带隙拓扑的基础上,提出了一种高精度、低温漂带隙电压源电路的设计方案。同时,提出一种寻找并消除简并点的理论方法,用于指导启动电路的设计。设计的电路在XFAB0.6μm CMOS工艺上流片成功。测试结果表明:在2.45-16V电压范围内,该电压基准源的电压精度为1.202±0.2mV;在-10~80℃范围内,温度系数为7.6~9ppm/℃;最大功耗0.32mW。 A high-precision and low-temperature voltage reference source was proposed based on classical topology of voltage reference, and theory of finding and canceling degeneration for designing start-up circuit was presented. The circuit was implemented in XFAB's 0. 6μm CMOS process. Test results showed that the reference source had a voltage precision of 1. 202 ±0. 2 mV at 2. 45 V to 16 V, and a temperature coefficient between 7. 6 ppm/℃ and 9 ppm/℃ in the temperature range from -10 ℃ to 80 ℃, with a max power of 0. 32 mW.
