According to the fact that voltage follower of traditional second-generation current conveyor （CCII） is unsatisfatory, a new second-generation current conveyor（CCCII） is proposed. A current controlled second-order bandpass filter, operating in the current mode, is also described and designed. Constituting the second-order current-mode bandpass through using of the new second-generation current conveyor （CCCII）, and only two CCCII＋s and two capacitors could complete the design. The structure of the design is simple. Its central frequency can be adjusted by acting on the bias current of the conveyors. HSpice software was used to simulation analysis and verify the accuracy and feasibility of the theoretical design.
