A design tool for high-resolution high-frequency cascade continuous- time Σ∆ modulators. Proceedings of SPIE, 6590, 659016.0277-786X (Impreso)1996-756X (electrónico)https://hdl.handle.net/11441/88355Event: Microtechnologies for the New Millennium, 2007, Maspalomas, Gran Canaria, SpainThis paper introduces a CAD methodology to assist the de signer in the implementation of continuous-time (CT) cas- cade Σ∆ modulators. The salient features of this methodology ar e: (a) flexible behavioral modeling for optimum accuracy- efficiency trade-offs at different stages of the top-down synthesis process; (b) direct synthesis in the continuous-time domain for minimum circuit complexity and sensitivity; a nd (c) mixed knowledge-based and optimization-based architec- tural exploration and specification transmission for enhanced circuit performance. The applicability of this methodology will be illustrated via the design of a 12 bit 20 MHz CT Σ∆ modulator in a 1.2V 130nm CMOS technology.application/pdfengAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Continuous-time Σ∆ ModulatorsHigh-resolution High-frequency Data ConvertersDesign AutomationCADinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess10.1117/12.721896
