A systematic method of designing multiple loop feedback current mode nth order lowpass filter based on multiple outputs current controlled conveyor is presented.Different kinds of nth order low pass filter structure are obtained by this method.The proposed nth order filter is constructed by n CCCIIs and n grounded capacitors.PSpice simulation for an actual circuit is conducted,and the result shows that the proposed circuit is valid and effective.
