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 - QFN and SON PCB Attachment (Rev. B)PDF, 821 Kb, Revisión: B, Archivo publicado: agosto 24, 2018
