A new way to design n-order OTA and MOCCCII current-mode versatile filter was presented. This method was based on analyzing a transfer function of n-order generic current mode filter,and generating n number of realizable transfer function using lossless integrator. Selecting proper input current signal,low pass,high pass,band pass and band stop filters could be realized just by suitably choosing the external current signals while internal structure of circuit and amount of elements don’t need to be changed. Compared with similar circuit,the filter has the advantages of simpler and more convenient design. The circuits were easy to be integrated for all grounded ca-pacitors. The filter could be applied to signal processes of communication and electronic measure and instrument. The fifth-order filter was designed. PSPICE simulation result was consistent with the theoretical analysis,and verifies the feasibility of this method.
