Abstract

There are many cases in which standard reference voltage sources exhibit a number of flaws, in particular, unipolarity and a high thermal voltage coefficient. The latter flaw is especially important, as reference voltage sources are used, as a rule, in a broad range of temperatures. This article considers the technique of approximation piecewise stabilization of the thermal voltage coefficient and the circuit design for constructing a bipolar source of reference voltage with a low temperature coefficient, a source that is configured on the basis of standard integrated circuits of operational amplifiers. In terms of thermal voltage coefficient, the proposed circuit design is among the best examples of commercial reference voltage sources usable in a broad range of feeding voltages and characterized by bipolar output voltages.

参考电压源热电压系数的近似分段稳定

摘要

在许多情况下，标准参考电压源表现出许多缺陷，特别是单极性和高热电压系数。后一种缺陷尤其重要，因为通常在较宽的温度范围内使用参考电压源。本文考虑了热电压系数的近似分段稳定化技术以及用于构建具有低温度系数的双极性参考电压源的电路设计，该源是基于运算放大器的标准集成电路配置的。就热电压系数而言，拟议的电路设计是可广泛用于馈电电压且以双极性输出电压为特征的商用参考电压源的最佳示例。
