Abstract
A power-over-Ethernet (PoE) powered device (PD) includes a PoE interface to receive a connector of an ethernet cable to connect the PD to a PoE power sourcing equipment (PSE). The PD includes a first power line connected to the PoE interface to receive PoE power from the PSE in a connected state of the PD to the PSE. The PD also includes a rectifier including a first input connected to the first power line, a first output connected to a first terminal of a PD chip, and a first rectifying element connected between the first input and first output. The PD further includes a first capacitor connected in parallel to the first rectifying element between the first input and the first output. AC noise appearing on the first power line is bypassed around the first rectifying element via the first capacitor.
