An integrated tool called DAISY (Delta-Sigma Analysis and Synthesis) is presented for the high-level synthesis of ΔΣ modulators. The approach determines both the optimum modulator topology and the required building block specifications, such that the system specifications -- mainly accuracy and signal bandwidth -- are satisfied at the lowest possible power consumption. A genetic-based differential evolution algorithm is used in combination with a fast dedicated behavioral simulator that includes the major nonidealities of the building blocks to realistically analyze and optimize the modulator performance. Experimental results illustrate the effectiveness of the approach. Also, an overview of optimized topologies as a function of the modulator specifications for a wide range of values shows the capabilities and performance range covered by the tool.
