Abstract
This paper presents a new realization of electronically tunable voltage-mode universal filter with three-input five-output using operational transconductance amplifiers. The proposed filter circuit offers the following attractive feature: employment of grounded capacitors which is more suitable for integrated circuit implementation, simultaneous realization of all the standard filtering functions; orthogonal control of ω o and Q and no requirement of inverting-type input signals which is require no addition circuit. PSPICE simulation results are given to verify the presented theory. © 2011 IEEE.
