- 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:提出了一種采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,在不同子區間上采用不同線性補償函數達到最佳補償.由于溫度區間縮小,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 / - An off - line algorithm of constrained model predictive control based on piecewise - linear feedback control law is presented to solve its potentially high on - line computational demand . the piecewise - linear feedback control law is off - line computed by lmi optimization problems and the on - line control computation reduces to the simple evaluation of the defined piecewise linear function , which makes the online computational efficiency significantly improved . 4
