total current detection of distributed load circuits independent of current distribution using distributed voltage averaging

摘要

aspects to detect total current of distributed load circuits (102) regardless of a spatial profile of the total current using distributed voltage promediation are revealed. in one aspect, a current detection circuit (100) is configured to detect the total current of a distributed load circuit regardless of where the current is distributed. the current detection circuit includes distributed voltage promediation circuits (112 (1), 112 (2)) configured to determine average voltages of the distributed load circuit based on voltages detected in multiple resistive paths (108 (1) - 108 (n)) corresponding to a distribution network configured to supply voltage to the distributed load circuit. an amplifier (134) includes an output node that has an output voltage (vout) that is proportional to the total current flowing in the distributed load circuit. the current detection circuit allows to detect total current regardless of where the current flows, providing more accurate current detection compared to current detection in an area of the distributed load circuit.
