  13. 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
