4.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/℃.收藏指正
