Abstract
Official abstract text for this publication.
In a particular embodiment, a method of producing a powered device detection signature includes rectifying a device detection input received from a powered network to produce a rectified detection input at a powered device. The method further includes applying the rectified detection input to a signature resistor and to a variable impedance circuit in parallel with the signature resistor to produce a device signature that is substantially constant over a power range associated with the device detection input.
First claim
Opening claim text (preview).
What is claimed is: 1. A powered device comprising: an input configured to couple to a Power over Ethernet network to receive a device detection signal from a power sourcing equipment device; a signature resistor coupled to the input; and a variable impedance circuit coupled to the input in parallel with the signature resistor, the variable impedance circuit having an impedance that increases as a current associated with the device detection signal increases, the signature res…
