Impedance projection based transconductance amplifier

A current feedback technique is proposed to realise the transposition of grounded impedance to a floating impedance or transconductance. This technique, that can be viewed as an impedance projection, also allows one to implement a new current conveyor topology and to extend applications based on transconductance amplification. A theoretical approach of this new technique using a grounded impedance, two classical transconductance amplifiers and one second generation current conveyor only is presented.
