ABSTRACT:
A differential to single-ended converter includes a voltage-to-current converter that converts differential voltage input signals to differential current signals which differ by a difference current. A current mirror mirrors the first differential current signal. A substantially constant DC voltage level is established. A resistor conducts any difference in current between the mirrored current and the second differential current signal and translates this difference current to a single-ended voltage output signal. An input buffer provides the differential voltage input signals to the voltage-to-current converters.
