发明名称 Sigma-delta modulator with DAC resolution less than ADC resolution
摘要 A sigma-delta modulator is provided with a feedback digital-to-analog converter having less resolution than the quantizer, while providing a reduced length output word, requiring minimal additional internal processing, and shaping of the truncation error by an effective noise transfer function greater than the order of the host sigma-delta modulator.
