Realization of Universal Active Complex Filter Using CCIIs and CFCCIIs

摘要

In this paper, two universal building blocks for complex filterusing CCIIs, CFCCIIs, grounded resistors and grounded capacitors arepresented. These can be used to realize various complex bandpassfilters with arbitrary order. The pa- per shows that the responseerror of the proposed circuit caused by nonideality of activecomponents is more easily compensate than that of the conventionalone employing op-amps, and that the sensitivities for all componentsare relatively small. Experi- mental results are used for verifyingthe validity of the proposed circukits.
