摘要：

A　KHN(Kerwin-Huelsman-Newcomb)　current-mode　filter　circuit　based　on　MOCCII(second　generation　current　conveyor　with　multiple　outputs)　is　present.　The　circuit,　which　is　constructed　by　three　MOCCII　and　six　RC　elements,　can　realize　a　lowpass　filter,　a　bandpass　filter　and　a　highpass　filter　at　same　time.　By　a　simple　current　operation,　a　bandstop　filter　and　a　allpass　filter　can　be　obtained.　The　circuit　has　a　low　sensitivity　and　is　integrated　conveniently　for　RC　elements　are　grounded.　Compared　with　voltage-mode　KHN　filters　based　CCII　(second　generation　current　conveyor),　it　also　has　a　simper　structure　and　much　fewer　active　elements.　The　non-ideal　characteristic　of　MOCCII　is　analyzed,　and　compensation　method　is　present.　In　the　last,　The　circuit　PSPICE　imitation　results　before　compensation　and　after　compensation　are　given.
