Abstract

Single CFOA based voltage mode universal biquadratic filter is discussed. The current feedback operational amplifier (CFOA) is a very versatile active building block and is now commercially available from several manufacturers This is due to the wellknown fact that it offers some essential advantages such as wider signal bandwidth, higher linearity, larger dynamic range and smaller number of components, when compared to that of conventional voltage mode operational amplifier (VOA) counterparts. The aim of this design idea is to present a configuration for the realization of the voltage mode universal biquadratic filter with three inputs and one output, employing only one CFOA and five passive elements. The properties of the proposed multifunctional circuit were verified by computer simulations using the PSPICE program.
