Realization of Resistorless Wave Active Filter using Differential Voltage Current Controlled Conveyor Transconductance Amplifier
MetadataShow full item record
In this paper, a resistorless realization of high order voltage mode wave active filter based on Differential Voltage current controlled conveyor transconductance amplifier (DVCCCTA) is presented. The wave method is used for simulating reflected and incident wave for basic building block i.e. series inductor and configuring it for other passive element realization by making appropriate connection. The proposed structure uses grounded capacitors and possesses electronic tunability of cutoff frequency. The proposed approach is verified for a 4th order low pass filter through SPICE simulation using 0.25µm TSMC CMOS technology parameters.
