Abstract
Aspects of the invention include a circuit having a power header configured to couple to a power supply and to provide an output voltage. A sense circuit is coupled to the power header to receive the output voltage, the sense circuit including a replica voltage circuit coupled to a replica power header circuit and a transistor, the replica voltage circuit being configured to provide a replicated output voltage in accordance with the output voltage, the replica power header circuit being configured to couple to the power supply and the replicated output voltage to generate a replica current, the transistor being configured to deliver the replica current.
