Current controlled current conveyors and its applications

In this thesis, all types of current conveyors from the invention of the first type, first generation current conveyor, and their applications are discussed and the most emphasized one is current controlled current conveyor. The main variety of the current controlled current conveyor (CCCII) is providing electronic adjustibility by parasitic resistance. This parasitic resistance can be changed by applied bias current. Besides electronic tunability, CCCII has several advantages as less power consumption, less complex structures, and better frequency performance when it is compared with operational transconductance amplifier (OTA) and opamp. Because of its advantages, filters that have controllable functions according to center frequency, gain or quality factor, oscillators with adjustable frequency, and inductance simulations with controllable value are designed. Then, the proposed circuits are simulated by using PSpice simulation program and it is observed that simulation results confirm theory. During the design, it is tried to use minimum number of active and passive components.
