ABSTRACT: At present there is a growing interest in designing current mode circuits. This attributed to their large signal bandwidth, great linearity, wider dynamic range, simple circuitry and low power consumption. The paper 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 CMOS technology and is examined the performances through PSPICE simulations. The CCCCTA performs tuning over a wide current range. In addition, some circuits for example as a current-mode universal biquad filter and a grounded inductance occupy only single CCCCTA.
