Abstract
An integrated circuit includes a functional circuit and a power calibration and monitoring system including a digital-to-analog converter (DAC), a variable gain amplifier (VGA), and a counter. The DAC generates a differential pair of feedback currents based on a digital count. The VGA generates a differential pair of amplified signals based on a magnitude difference between the differential pair of feedback currents and a differential pair of detection currents derived from a differential pair of node voltages associated with the functional circuit. The counter generates the digital count based on the differential pair of amplified signals. The differential pair of feedback currents is controlled such that the magnitude difference between the differential pair of detection currents and the differential pair of feedback currents is within a tolerance limit. A power associated with the functional circuit is calibrated and monitored based on the digital count.
