A Study on the Series Inductance Simulator Using Single CFOA
Main Article Content
Abstract
In this communication, we introduce a novel series-type lossy inductor simulator. The circuit consists of a single current feedback operational amplifier (CFOA), three resistors, and one capacitor. Control over the inductance can be achieved independently by adjusting a grounded resistor. Electronic control of the inductance is also possible by substituting the resistor with its MOS equivalents. The proposed circuit finds application in designing a lead compensator and low pass filter (LPF). To validate its functionality, a CMOS CFOA is utilized in the PSPICE simulator. Simulation results confirm the operation of the proposed circuits, closely matching theoretical predictions.
