  • Digital Filter Types in Delta-Sigma ADCs
    PDF, 219 Kb, 档案已发布: Jun 27, 2017
    This application report discusses digital filters which are a ubiquitous feature in delta-sigma analog todigital converters (ADCs). Digital low-pass filters are essential to the functionality of a delta-sigma ADCwhich relies on oversampling and noise shaping to push quantization noise out of band. There arevariations between the types of digital filters used in delta-sigma ADCs that provide
