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:提出了一种采用分段线性补偿的方法来实现高精度带隙基准,其基本原理是将整个温度区间分为若干个子区间,在不同子区间上采用不同线性补偿函数达到最佳补偿.由于温度区间缩小,补偿误差也随之减小,从而在整个工作温度间上的补偿误差也缩小.理论上,只要温度子区间取得足够小,就可以达到任意精度.示例中将- 40 120的温度区间仅分为三个子区间,平均温度系数就从1 . 5 10 - 5 /减小到2 10 - 6 /
