Uni Ulm Sigma-Delta Synthesis Environment

The Uni Ulm Sigma-Delta Synthesis Environment is a web-based design environment for ΣΔ ADCs based on a heuristic search. I comprises tools for lowpass and bandpass ΣΔ modulators as well as incremental ΣΔ ADCs. For continuous-time modulators, it allows the direct design of the modulator including non-idealities within extremly short response times. There is no need of a subsequent transformation from discrete-time to continuous-time.

This environment is freely available at no charge (see Terms of Use for more information)!
