Abstract
Systems and methods of measuring current in a power over Ethernet (PoE) system are provided. The PoE system includes an integrated circuit component having a controller, an internal transistor, a replica transistor, and an external transistor. Current in the system can be indirectly measured by enabling and disabling the transistors in known ways and then measuring the current through the replica transistor. The actual current in the system can be calculated based on the measured currents, thereby allowing for a PoE system that is capable of measuring current without a resistor in series with the external transistor.
