| Abstract: | A fully differential second-order current mode MOCCII based filter with multi-function is presented in the paper. The second-order low-pass, band-pass and high-pass filters can be realized simultaneously. By connecting outputs appropriately, band-stop and all-pass filters can be obtained. The PSPICE simulation of proposed circuit is made. The circuit can restrain odd order harmonic distortion and common model disturbing signal. In the end, the non-ideal characteristic of MOCCII is analyzed and a compensation method is proposed. |
