A New High Order Current Mode Filter with Multiple Inputs and Single Output Based on MOCCCII

A new high order current mode filter circuit with multiple inputs and one output based on MOCCCII is presented. The filter circuit which only contains n active elements, n capacitors and not any resistance element can produce high order low-pass, band-pass, high-pass, band-stop and all-pass filters. Various kinds of filters can be realized just by changing the amount and mode of joining external current signals to the circuit, and internal structure of circuit and amount of elements need not change, and the circuit is convenient to be integrated. PSPICE simulation for an actual circuit is conducted, and the result shows that the proposed circuit is valid and effective
