Abstract: An apparatus including a printed circuit board (PCB) including a sense resistor; and an integrated circuit (IC) mounted on the PCB, wherein at least a portion of the IC draws current from a power rail, wherein the sense resistor is coupled between the power rail and the IC, wherein the sense resistor is configured to produce a sense voltage in response to the current drawn by the at least portion of the IC, and wherein the IC includes a current sensor configured to generate a signal indicative of the current drawn by the at least portion of the IC based on the sense voltage.

Abstract: Various embodiments include power management system methods including receiving, at a processor(s), a notification signal triggering the processor(s) to implement power usage mitigation at the processor(s), determining, by the processor(s), a mitigation amount of power rail power by which to mitigate current usage at a power rail based on a use case for the power rail, and implementing power usage mitigation at the processor(s) by the processor(s) sufficient to mitigate power usage at the power rail by the mitigation amount of power rail power. Power usage mitigation may include reducing processor(s) current usage: by a predefined amount; proportional to the amount a power rail current exceeds a power rail current threshold; by the amount of current exceeding a processor current threshold; or by a smallest amount between the amount a power rail current exceeds a power rail current threshold and the processor(s) current exceeds a processor current threshold.

Abstract: In an aspect, measurement processing circuitry may obtain, from a sensor, a first measured value of a measured object, the first measured value corresponding to a first power consumption level of the measured object at a first time point. The measurement processing circuitry may obtain, from the sensor, one or more second measured values of the measured object, the one or more second measured values corresponding to one or more second power consumption levels of the measured object at one or more second time points earlier than the first time point. The measurement processing circuitry may determine a corrected value based on the first measured value and the one or more second measured values, the corrected value representing the first power consumption level of the measured object at the first time point.
