Nth order voltage mode low-pass filter using current conveyors

A new configuration realizing Nth-order low-pass filter involving second generation current conveyors is presented. All the current conveyors are of the positive type (CCII+). The proposed configuration allows the use of four capacitances, four resistances and four (CCII+). The use of this active component makes the implementation simple and attractive. The functionality of the circuit is tested using PSPICE simulator for a 0.35µm CMOS process model. The proposed circuit is able to operate at low supply voltage (± 0.75V ). Simulation results are included to demonstrate the results.
