Abstract
A current mirror amplifier (CMA) and another current amplifier are connected in a degenerative current feedback loop with a point therein which point exhibits a low a-c impedance with respect to a-c ground and provides for sensing signal current applied thereto from an impedance element. The CMA has an input terminal connected to this sensing point, a common terminal connected to a-c ground and an output terminal connected to a constant current source load. The other current amplifier has input and common terminals connected to the CMA output terminal and to the sensing point, respectively, and has an output terminal from which sensed signal current is available.
