Current-controlled CCDDCC with controlled current gain

This paper presents a new active building block for analog signal processing, called the current-controlled differential difference current conveyor (CCDDCC) with controlled current gain. Its parasitic resistance at X-terminal can be controlled by an external bias current and the current at Z-terminal can be electronically controlled by a current ratio and can be made insensitive to temperature and integrated circuit processing. PSPICE simulation results of proposed CCDDCC with controlled current gain and its application are also presented.
