提出了一种新颖的无辅助电路的带隙基准(BGR)电路的温度补偿方法。通过使用具有指定温度系数(TC)的电阻组合(由不同类型的电阻组成)，先前报告的带隙基准的温度系数从22.11ppm/°C提高到3.499 ppm/°C(−25°C-85°C)。为了实现这一改进，还提出了一个有用的模型来帮助理解电阻组合的TCS与BGR之间的关系。
In this paper, an original method is proposed to implement temperature compensation for a bandgap reference (BGR) circuit without any auxiliary circuits. By employing resistor combinations (formed by different type of resistors) with specified temperature coefficients (TC), the temperature coefficient of a previous reported bandgap reference is improved from 22.11 ppm/°C to 3.499 ppm/°C (−25°C–85°C). In order to accomplish the improvement, a useful model is also proposed to help understand the relationship among the TCs of resistors’ combinations and BGR.
