CCII based multifunction inverse filter

In this paper, we proposed a number of new inverse highpass (IHP), inverse bandpass (IBP), and inverse lowpass (ILP) filters using second generation current conveyor (CCII) as building blocks. The proposed two topologies can be configured as one of the above mentioned inversed filter by the selection of appropriate admittance. To test the functionality of the proposed multifunction inverse filter, the circuit was simulated using PSPICE simulator software. In simulation of the circuits, the CCII circuit was designed using macro model of AD844 IC. The simulated results are well agreed with the theoretical results.
