Abstract: A new second-order universal active current-mode filter based on MO-CCII is presented.The filters have one output and three inputs.Each kind of filter such as  low-pass,high-pass,band-pass,notch and all-pass filter can be obtained by selecting the corresponding input signal combinations.The proposed circuit is with simple structure,separately adjustable centre frequency and the quality factor,all grounded passive components and low passive sensitivities.Theoretical analysis and spice simulation indicate that the proposed circuit is effective and feasible.

Key words: current-mode circuit, MO-CCII(second generation current conveyor with Multiple outputs), universal active filter
