Patent ID: 7646214

Claim:
A signal line termination configured to terminate a signal line, the signal line termination comprising a first circuit having an input to be coupled to the signal line and a first output to be coupled to a device co-located with the first circuit, the first circuit to provide electrical power to the device, the first circuit comprising: an impedance-matching portion connected to the input to match an impedance of the signal line, wherein the impedance-matching portion comprises reactive components; and a power-harvesting portion coupled between the impedance-matching portion and the first output to convert a portion of energy in a signal on the signal line to DC electrical power to be provided to the device through the first output, wherein the impedance-matching portion is configured to reduce reflections on the signal line caused by impedance mismatch, and wherein the portion of energy in the signal converted to DC electrical power by the power-harvesting portion corresponds at least to an amount the reflections are reduced by.
