ABSTRACT: In this paper we present a wave active filter based on Voltage
Differencing Transconductance Amplifiers (VDTAs). The synthesis of active
filters basically based on processing of wave quantities. The wave method is
presented for basic building blocks of active filters i.e. a series
inductor and parallel capacitor through which realization of various active
circuits is made by appropriate connections. The proposed wave active filter is
verified by realizing a 4th order low pass Butterworth filter using
SPICE simulation with 0.18 μm TSMC CMOS technology parameters.
