Abstract :
A single-chip 30-channel data acquisition system for power management applications has been successfully designed, fabricated, and tested. This mixed analog/digital single-chip system is composed of three delta-sigma A/D (analog-to-digital converters which have 11 bits of resolution each and an oversample clock of 3.58 MHz. The dedicated digital signal processor has a 32-bit two´s-complement, fixed-point architecture and performs low-pass filtering, accumulation, and data selection and comparison
