Abstract
Dynamic insertion insertion loss for an ethernet power on differential cable pairs is shown in a power feed circuit that supplies power to a network attached device (PD). An insertion loss control circuit limits power loss in a coupled power feed circuit. determines an insertion loss limit, and senses an average power of the power signals to produce a common mode feedback signal to the power feed circuit.
