HDL-A MODELLING OF SWITCHED-CURRENT DELTA SIGMA A/D CONVERTERS

C. Rubio, S. Bota, J. G. Macías, J. Samitier
  • Abstract:
    Switched Current (SI) is a very interesting analog technique to perform interface circuits in mixed analog/digital systems because it is compatible with a low cost digital CMOS process (single poly technologies). The attempt of this work is to shed some light on the SI delta-sigma converter design method making use of an analog Hardware Description Language. To demonstrate the performances of the HDL-A model to optimize delta-sigma converters, a first order SI delta-sigma modulator has been designed, simulated and implemented using a 0.7 mm CMOS digital process. Also we have compared the simulated results and the experimental.
