Abstract :
This article presents a basic current-mode building block for analog signal processing, namely current controlled current conveyor transconductance amplifier (CCCCTA). Its parasitic resistance at current input port can be controlled by an input bias current. It is very suitable to use in a current-mode signal processing, which is continually more popular than a voltage one. The proposed element is realized in a bipolar technology and is examined the performances through PSPICE simulations. They display usabilities of the new active element. The CCCCTA performs tuning over a wide current range. In addition, some examples as a current-mode universal biquad filter and a grounded inductance simulator are included. They occupy only single CCCCTA.
