Abstract
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.
