Vector Switching Generalizes D/A Noise Shaping
- ABSTRACT:
- The most promising approach to obtaining the
extraordinary in-band precision required of the
internal DAC in multibit delta-sigma converters is
dynamic element matching, in which errors due to
DAC-hardware mismatch are spectrally shaped to avoid
the signal band. Here we propose an architecture
based on a vector switching signal and offer a
mathematical framework for the analysis and design of
such systems.
