摘要

使用Microcap电路分析包研究了一种测量电路，该电路将阶跃电压与电路串联施加到介电样品上，并使用运算放大器提供适合驱动记录设备的输出。作者研究了将运算放大器以两种不同的模式连接到电路中的效果:电压跟随器模式和电流-电压转换模式。对偏置电压、偏置电流和偏置电流的处理进行了描述。给出了AD515L运算放大器和AD310/311运算放大器的测试结果。讨论了放大器的最小可接受性能。

Analysis of a dielectric measuring circuit using commercial software

The Microcap circuit-analysis package was used to study a measuring circuit when a step voltage is applied to a dielectric specimen in series with the circuit and an operational amplifier is employed to provide an output suitable for driving a recording device. The authors investigated the effects of connecting an operational amplifier into the circuit in two different modes: the voltage-follower mode and the current-voltage converter mode. The treatment of the offset voltage, bias current, and offset current is described. Results are given for the AD515L operational amplifier and the AD310/311 operational amplifier. The minimum acceptable amplifier performance is discussed.<>
