Abstract
A conversion circuit in a transceiver system is capable of converting a single-ended input voltage signal to balanced differential output signals. An input voltage signal can be referenced to the ground (zero voltage) GND and can travel both above and below the zero voltage. A plurality of feedback circuits, having a plurality of transistors and a plurality of resistances, disposed and coupled in a mirror image, to boost an input impedance to an output impedance of a gain of one of the transistors, to isolate an output load from an input of the conversion circuit, and to provide a voltage gain from the input to an output determined by the plurality of resistances.
