摘要：
A method of self-calibrating a modulator includes at least one integrator likely to incur a phase error may include reading a pulse response of the modulator, calculating a phase error parameter of the at least one integrator, and calibrating the phase error parameter. In addition, the calibration may provide a count of pulse response samples above suitable threshold values, as well as a change in the value of a capacitor associated with the integrator based upon the sample count.
