模拟积分器性能的实验分析及泄漏电阻的测量
Property analysis of the analog integrator and the measurement of the capacitor leakage resistance
摘要
Abstract
A long time low-drift integrator is of great importance in the application in Tokamak research. Owing to the great influence of heat and humidity on the integrator operational-amplifier(op-amp) stabilities, experimental measurements of the effect of heat and humidity on the op-amp are conducted and the regularities are obtained. The results will be helpful to the design of the high performance integrator. One of the main reasons causing the drift of integrator is the leakage resistance of the integral capacitor. One method to measure the equivalent leakage resistance of capacitor is presented and an approximate relationship function between the capacitance and the voltage is given.关键词
