Current controlled current conveyor with positive and negative parasitic resistance

In this study, a circuit that can be realize two different controlled current conveyor on the same structure is proposed. Being used different connection structures on the proposed circuit with this new design, the circuit can be used being controlled current conveyor with positive parasitic resistance or being controlled current conveyor with negative parasitic resistance when it is requested. The theoretical analysis of proposed circuits has been done and the circuit performances have been corroborated with Pspice simulation results. It is proved that the parasitic resistance can be adjusted between ±52 Ω and ±520 kΩ for both type of the current conveyors depending on simulation results. It is shown that proposed circuit structure can be used being a convenient structure in realization of many analog signal processing circuits based on bipolar technology and can be electronically adjustable.
