摘要: 提高温度稳定性和展宽恒定电流范围是当前恒流器件应用中的两个突出问题。现有根据长沟道场效应原理制备的两端恒流器件,由于工作机理限制已难指望在上述问题上取得有效的进展。本文介绍一种恒流源电路的模块设计思路,新近研制了在很宽电流范围内连续可调的新恒流器件。测试结果表明,该器件样管的输出电流可达0.1A～8A,电流温度系数低达10-4/℃10-5/℃。起始电压低于0.4 V,是一种输出电流范围又宽、稳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
