This paper presents two kinds of multi-input-multi-output CCⅡ (second generation current conveyor) voltage-mode filter circuits. The first kind of filter circuits with three inputs and two outputs is constructed by two CCⅡ+(plus type of CCⅡ) and four RC elements. It can realize ten filters. Besides, four kinds of filters with double simultaneous outputs can be realized. The second kind filter circuit with four inputs and two outputs is constructed by one CCⅡ+, one CCⅡ- (minus type of CCⅡ) and five RC elements. It can realize 22 filters. In addition, six kinds of filters with double simultaneous outputs can be realized. Compared with similar circuit, the circuits in this paper have simpler structures and stronger functions. We also give realization circuits of CCⅡ(including CCⅡ+ and CCⅡ-) and make experiment on the proposed circuits.
