Huang Man-chi · Modern Electronics Technique · 2007
A circuit of high order filter using CFA is presented based on the signal-flow graph.The configuration of circuit which is consisted of CFA,resistances and capacitances can realize lowpass,bandpass,highpass,notch filters by only changing impedances.As an application of the proposed circuit,the realization of a four-order bandpass filter and a five-order highpass filter are proved using PSPICE simulations,which verify the proposed configuration is applicable.
