Single operational transresistance amplifier‐based grounded resistance‐controlled synthetic inductor configuration

Abstract

In this paper, a grounded lossy inductance (parallel RL type) simulator circuit employing an operational transresistance amplifier (OTRA), five resistors, and a virtually grounded capacitor is proposed. The value of simulated inductor can be controlled independently through a grounded resistance and/or virtually grounded capacitor without affecting the parallel equivalent resistance. Application examples using the presented lossy inductor have been provided. The performance of the application examples has been verified by sample experimental results employing an OTRA implemented using AD844‐type current feedback operational amplifiers.
