MINLP Based Topology Synthesis for Delta-Sigma Modulators Optimized for

This paper proposes anovel architecture synthesis algorithm for single-loop single-bit∆Σmodulators. We defined a generic modulator architecture and derived its noise and signal trans-fer function (NTF/STF) in symbolic forms. We then used the TF in MINLP to generate optimal topologies for a variety of design requirement, such as modulator complexity, sensitiv-ity and power consumption, which appeard as cost functions. Experiments show the superiority of synthesized topologies as compared to traditional solutions. 1
