摘要
本文提出了一种基于双极性工艺的高性能带隙基准电压源的设计。该电路结构简单,性能优异。用Spectre进行仿真,结果表明,在-50～90℃的温度范围内,其温度系数为5.7ppm/℃;在3～15V的电源电压内,电源线性调整率为1.0mv/V,电源抑制比(PSRR)为-55dB。
Design of a high precision bandgap voltage reference circuit based on bipolar technology is presented in this paper. The structure of the circuit is very simple and the performance is excellent. The simulation results with Candenee Spectre show that the temperature coefficient is about 5.7 ppm/℃ in the temperature range from -50-90℃. The line regulator is 1.0mV/V using the power supply voltage range from 3V to 15V and the power supply rejection ration （PSRR） is -55dB.
