Abstract :
High-level design tools and architecture libraries have been developed for the analysis and design of digital decimation filters for oversampling A/D (analog-to-digital) converters. Results from a 14-bit signal acquisition module designed with these tools are presented. The chip was optimized for a decimation ratio of 256, a sampling rate of 20 kHz, a passband extending to 9 kHz with less than 0.2 dB of ripple, and 65 dB of out-of-band attenuation
