Abstract : a bandgap voltage reference is presented with a piecewise - linear compensating circuit in order to reduce the temperature coefficient. the basic principle is to divide the whole operating temperature range into some sub - ranges. at different temperature sub - ranges the bandgap reference can be compensated by different linear functions. since the temperature sub - range is much narrower than the whole range, the compensation error can be reduced significantly. theoretically, the precision can be improved unlimitedly if the sub - ranges are narrow enough. in the given example, with only three temperature sub - ranges, the temperature coefficient of a conventional bandgap reference drops from 1. 5 10 - 5 / to 2 10 - 6 / over the - 40 to 120 temperature range
文摘:提出了一種採用分段線性補償的方法來實現高精度帶隙基準，其基本原理是將整個溫度區間分為若干個子區間，在不同子區間上採用不同線性補償函數達到最佳補償.由於溫度區間縮小，補償誤差也隨之減小，從而在整個工作溫度間上的補償誤差也縮小.理論上，只要溫度子區間取得足夠小，就可以達到任意精度.示例中將- 40 120的溫度區間僅分為三個子區間，平均溫度系數就從1 . 5 10 - 5 /減小到2 10 - 6 /
