Abstract —An integrated tool called DAISY (Delta–Sigma Analysis and Synthesis) is presented for the high–level synthesis of 16 modulators. The approach determines both the optimum modulator topology and the re-quired building block specifications, such that the system specifications – mainly accuracy and signal bandwidth – are satisfied at the lowest possi-ble power consumption. A genetic–based differential evolution algorithm is used in combination with a fast dedicated behavioral simulator that in-cludes 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 topolo-gies as a function of the modulator specifications for a wide range of values shows the capabilities and performance range covered by the tool. I
