This paper presents a high-level synthesis methodology based on the use of multi-objective evolutionary algorithms for the optimization of ΣΔ modulators. Compared to conventional approaches, the proposed method allows to explore a number of different design objectives simultaneously in the design space in order to find out the best sets of target specifications — defined as Pareto-optimal fronts. This strategy leads to more efficient designs in terms of effective resolution, bandwidth and power consumption. As an application, the proposed method is applied to the high-level design of a 65-nm CMOS LC-based fourth-order band-pass continuous-time ΣΔ modulator, showing a number of experiments to validate the presented approach1.
