Abstract
A circuit for calibrating selective coefficients of a delta-sigma modulator is provided. The circuit includes a calibration logic module that is coupled to one of a plurality of stages of the delta-sigma modulator. The calibration logic module measures the oscillating frequency of a respective stage and compares it to a reference frequency. The calibration logic adjusts a selective circuit component associated with the respective stage so that the reference frequency and the oscillating frequency match.
