Abstract

This contribution deals with special first-order filtering structure design based on two operational transconductance amplifiers (OTAs) and single electronically controllable current conveyor of second generation (ECCII). Controllable parameters of OTAs and ECCII allow electronic reconnection-less reconfiguration among several types of transfer functions. Theoretical assumptions are supported by PSpice simulations with models of commercially available real devices.
