摘　　要：为降低传统双极结型晶体管(Bipolar Junction Transistor,BJT)型带隙基准源温度系数高的问题,提出了一种带有高阶曲率补偿的带隙基准电压源,极大降低了带隙基准源的温度系数.设计基于传统BJT型带隙基准电路,采用高阶曲率补偿电路对温度系数进行优化,并采用折叠式cascode运算放大器和自偏置cascode电流镜对输入电压范围进行优化.设计的带隙基准源具有低温度系数、高电源电压抑制比、结构简单的优点,是各类片上系统的优良选择.In order to reduce the problem of high temperature coefficient of the traditional BJT bandgap reference source,a bandgap voltage reference source with high-order curvature compensation is proposed,which greatly reduces the temperature coefficient of the reference source.Based on a traditional BJT bandgap reference circuit,a high-order curvature compensation circuit is used to optimize the temperature coefficient,and a folded cascode operational amplifier and a self-biased cascode current mirror are used to optimize the input voltage range.The bandgap reference source designed in this paper has the advantages of low temperature coefficient,high power supply rejection ratio and simple structure,and is therefore a superior choice for System on Chip.
