This article describes an instrumentation amplifier circuit by using current controlled current conveyors transconductance amplifiers (CCCCTAs). The circuit provides high input impedance which is a desirable feature for instrumentation amplifier. The proposed circuit can also be electronically adjustable gain and using only active components. Furthermore, the circuit enables to operate with the low temperature-sensitive. Consequently, the proposed circuit is very suitable for further fabricating into integrated circuit (IC) form to employ in a sensitive environment system. Moreover, the proposed circuit can provide in both output voltage and current signals. Performances of the proposed circuit are confirmed through PSPICE simulation results, they are in accordant to theoretical explanations.
