Abstract:
It is presented a general model circuit and structural design theory of current mode biquad filters based on MOCCCIIs (current controlled second generation current conveyor with multiple outputs).Various structures of filters can be produced by means of the model and the theory.Each structure can realize lowpass,bandpass,highpass,bandstop and allpass filters,or several kinds of them.There are not resistors in the filters.Capacitors are only passive elements of the filters,and they are all grounded.In addition,sensitivities of the circuits are very low.In the last,the PSPICE simulation to the introduced MOCCCII and the proposed filters is made.
