A Programmable and Configurable ASIC to Generate Piecewise-Affine Functions Defined Over General Partitions. IEEE Transactions on Circuits and Systems I: Regular Papers, 60 (12), 3182-3194.1549-8328https://hdl.handle.net/11441/105992This paper presents a programmable and configurable architecture and its inclusion in an Application Specific Integrated Circuit (ASIC) to generate Piecewise-Affine (PWA) functions. A Generic PWA form (PWAG) has been selected for integration, because of its suitability to implement any PWA function without resorting to approximation. The design of the ASIC in a 90 nm TSMC technology, its integration, test and characterization through different examples are detailed in the paper. Furthermore, the ASIC verification using an ASIC-in-the-loop methodology for embedded control applications is presented. To assess the characteristics of this verification, the double-integrator, a usual control application example has been considered. Experimental results validate the proposed architecture and the ASIC implementation.application/pdf13engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Digital architecturesEmbedded controlNonlinear circuitsPiecewise-affine (PWA) functionsVLSI implementationinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccess10.1109/TCSI.2013.2265962
