  • 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(bǔ)償?shù)姆椒▉?lái)實(shí)現(xiàn)高精度帶隙基準(zhǔn),其基本原理是將整個(gè)溫度區(qū)間分為若干個(gè)子區(qū)間,在不同子區(qū)間上采用不同線性補(bǔ)償函數(shù)達(dá)到最佳補(bǔ)償.由于溫度區(qū)間縮小,補(bǔ)償誤差也隨之減小,從而在整個(gè)工作溫度間上的補(bǔ)償誤差也縮小.理論上,只要溫度子區(qū)間取得足夠小,就可以達(dá)到任意精度.示例中將- 40 120的溫度區(qū)間僅分為三個(gè)子區(qū)間,平均溫度系數(shù)就從1 . 5 10 - 5 /減小到2 10 - 6 /
