摘要
带隙基准电路可以在电源电压、温度及工艺的变化环境中产生稳定的参考电压,广泛应用于模拟集成电路、数模混合集成电路和系统集成芯片(SOC)中,其精度决定了整个系统的精度和良率。带隙基准电路有许多性能指标参数,如温度系数曲线,基准值的精度,电路的功耗、电源抑制比等。另外带隙基准电路的难点是电路中存在多个简并点,电路的启动问题是难点也是重点。
Bandgap reference circuit can generate stable reference voltage in the changing environment of power supply voltage, temperature and process. It is widely used in analog integrated circuit, digital-analog hybrid integrated circuit and system integration chip(SOC). Its accuracy determines the accuracy and yield of the whole system.Bandgap reference circuit has many performance parameters, such as temperature coefficient curve, accuracy of reference value, circuit power consumption, power rejection ratio and so on. In addition, the difficulty of bandgap reference circuit is that there are many degenerate points in the circuit, and the starting of the circuit is also the key point.
