REALIZATION OF CURRENT CONTROLLED CONVEYOR MULTIMODE FILTERS

Abstract

Current mode circuits like current conveyors are getting significant attention in current analog ICs design due to their higher band-width, greater linearity, larger dynamic range, simpler circuitry, lower power consumption and less chip area. The second generation current controlled conveyor (CCCII) has the advantage of electronic tunability over the CCII . In CCCII adjustment of the X-terminal intrinsic resistance via a bias current is possible. The presented approach is based on the CMOS implementation of multiple output current controlled conveyor ( MO-CCCII) which is used to generate multiple loop feedback filter structure in transresistance mode , transadmittance mode and voltage mode . The circuit is used for its application in designing universal filter . All the circuits have been designed and simulated on PSPICE software with 0.35 m CMOS technology model parameters which is used to validate filter feasibility and operating frequency ranges using 2.5V supply voltage. Various simulations have been carried out to verify the valid filter expression . The outcomes show good agreement between expected and experimental results.
