摘要: A method, and apparatus, for calibrating a delta sigma modulator. The modulator includes an integrating amplifier circuit with capacitor producing output indicative of amount charge held on the integration capacitor. During calibration mode, feedback signal sampling section samples transfers packets corresponding to such sampled in each cycle input portion cycle. With arrangement, some is transferred thus reducing idle-tones.
