摘要
电压基准是模拟集成电路的重要单元模块,本文在0.35um BiCMOS工艺下设计了一个带隙基准电压源。仿真结果表明,该基准源电路在典型情况下输出电压为1.16302V,在-45℃~105℃范围内,其温度系数为3.6ppm/℃,在在电源电压为3V~3.6V范围内,参考电压从.16295V~1.16308V,变化了130uV,电源电压调整率为0.0186%/V。
voltage reference is a critical module in analog integrated circuit.this paper design a bandgap voltage reference,the simulation result demonstrate that the output voltage is 1.16302V in typical,the temperature coefficience is 3.6ppm/℃ When temperature from -45℃ to 105℃,the reference voltage is from 1.16295V to 1.16308V when power voltage 3V-3.6V,the vary Is 130uV.
