| 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. |
