- Digital Filter Types in Delta-Sigma ADCsPDF, 219 Kb, Archivo publicado: 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 - Analog-to-Digital Converter Grounding Practices Affect System Performance (Rev.
