This paper discusses and compares the effects of dynamic element matching (DEM) methods applied to the stochastic flash A-to-D converter (SFADC) to improve its linearity and noise behavior. Simulation results have shown that the application of DEM greatly improves linearity and SNDR behavior, and a simple random barrel-shift type of DEM is enough for 6-bit(More)
We report a hardware implementation of stochastic flash A-to-D converter (SFADC) with dynamic element matching (DEM) technique. For fast prototyping, the SFADC hardware was implemented on an FPGA board with 64 on-chip inverters using as comparators. The DEM circuit is implemented by analog multiplexer, which is put in front of the main SFADC. Measured(More)
