One operational amplifier simulator for third order systems with a leading time constant

Abstract

The paper outlines a method for the simulation of third order linear systems with only one operational amplifier. A particular class of the general third order systems, that is, systems with a leading time constant is considered in this paper. A basic circuit consisting of one operational amplifier, four capacitors and five resistors is presented. The circuit is a analyzed and the conditions of physical reliability discussed and obtained. The design formulae and procedure are also given.
