Abstract :
In this paper, the design and characterization of a 7-bit CMOS stochastic-flash analog-to-digital converter is illustrated by means of simulations including level-3 CMOS models and estimated dither-based spectra. The conversion scheme and its main properties are briefly recalled, and a possible design of the voltage reference generator proposed. It is shown that mismatches among the resistors in the ladder employed to generate these voltages are largely compensated by the presented architecture when small-scale dithering is employed
