Abstract: This paper presents a current-mode filter with three inputs and single output,which has only  one CCII-,one MOCCII,two grounded resistances and two grounded capacitances.The circuit not only is very simple,but also can carry out second-order five filtering functions.It is insensitive to R and C.PSPICE simulation result verifies that the proposed configuration is applicable.

Key words: MOCCII, current-mode, filter
