Abstract: A systematic method of designing nth-order multiple-loop feedback current-mode low-pass filter based on multiple-output current controlled conveyor(CCCII±)is presented.Different kinds of nth-order low-pass filter structure  can be obtained by this method.The proposed nth-order filter is constructed by n CCCIIs and n grounded capacitors.and is integrated conveniently for all the capacitors  grounded.Design example of 4th-order lowpass filter and computer simulation results of multiple-parameter sensitivity are also provided.

Key words: current-mode;current , controlled conveyor;multiple-loop feedback;active filter;sensitivity
