摘要: 提高溫度穩(wěn)定性和展寬恒定電流范圍是當(dāng)前恒流器件應(yīng)用中的兩個(gè)突出問題?，F(xiàn)有根據(jù)長溝道場(chǎng)效應(yīng)原理制備的兩端恒流器件,由于工作機(jī)理限制已難指望在上述問題上取得有效的進(jìn)展。本文介紹一種恒流源電路的模塊設(shè)計(jì)思路,新近研制了在很寬電流范圍內(nèi)連續(xù)可調(diào)的新恒流器件。測(cè)試結(jié)果表明,該器件樣管的輸出電流可達(dá)0.1A～8A,電流溫度系數(shù)低達(dá)10-4/℃10-5/℃。起始電壓低于0.4 V,是一種輸出電流范圍又寬、穩(wěn)定性又高的高性能器件。

Abstract: This paper introduces the designing thought of modular constant-current circuits and new-made current regulators with wide current range. Some data about the new device read as follows: current range is 0.1A-8A, current temperature coefficient is 10-4-10-5/℃, limiting-voltage is lower than 0.4V. It is a kind of excellent device with both high stability and wide current range -
