Abstract: In order to design multiple function current mode filter and make tune to filters, the authors present a signal flow graph of second order current mode filter and its corresponding MOCCII-based current mode filter whose parameters can be adjusted independently. The filter circuit is constructed by three MOCCIIs, three capacitors and four resistors. It can realize low-pass, band-pass, high-pass, band-stop and all-pass filtering outputs. The parameters (natural frequency and quality factor) of the filter can be adjusted independently. Moreover, the passive sensitivity and active sensitivity of the filter are very low. The proposed curcuit is computer-simulated and proved to be correct.
