模拟积分器的温度补偿

随着电子工业和自动化技术的发展,大时间常数的模拟积分电路在测量和控制领域中得到越来越广泛的应用。但是由于积分电容随温度变化而引起的积分误差,限制了它在精度要求较高的场合的应用。本文提出了一种用热敏电阻对其进行温度补偿的电路,并通过理论分析推导出了计算公式。该电路可以在较宽的温度范围内对温度的影响进行补偿。

Temperature Compensation of Analogy Interator

Along with the continuous development of electronics industry and automatic technique, the great time-constant analogy integral circuits are widely used in measurement and control systems.However, if a high accuracy is required,the integral error caused by varied temperature becomes too serious to be neglec- ted Therefore the applications of the circuits are limited. In this paper, a method of temperature-compensation is supplied.The method can compensate the influnce of the varied temperature in a wide range.
