Realization of Plus-Type CCCIIs Based Voltage Mode Universal Filter

A voltage mode universal filter with three-input and one-output using only two plus type current conveyors (CCII+), two resistors and two capacitors is presented. By replacing each CCII+ and a resistor at x port with plus type second generation current controlled conveyor (CCCII+) a new filter is proposed. The proposed structure has low sensitivity performance, low component spread and minimum requirement of hardware. Experimental and PSPICE simulation results confirm the workability of the proposed structure.
