Abstract
An on-chip low-voltage current sensing circuit for measuring current in an integrated circuit (IC). In one embodiment, an IC formed on a substrate, which includes a plurality of subcircuits, and a plurality of sensing circuits coupled to the plurality of subcircuits, respectively. The plurality of sensing circuits are configured to generate a plurality of currents, respectively, that are proportional to a plurality of load currents, respectively, consumed by the plurality of subcircuits, respectively, during operation thereof. A circuit is coupled to the plurality of sensing circuits and configured to generate a signal based on an aggregate of the plurality of currents.
