ABSTRACT:
A full-wave rectifier circuit is coupled to a pair of differential signal lines emanating from a computer. The differential signal lines which carry digital data information having a serial protocol scheme is tapped by the full-wave bridge rectifier to provide a power supply voltage to power various circuits coupled to the power supply. This scheme permits an interface unit to a serial protocol scheme of a computer to power itself from the data lines.
