(2005). Design Considerations for Multistandard Cascade ΣΔ Modulators. En Proceeding of the 2005 Conference on Design of Circuits and Integrated Systems, Lisboa (Portugal).https://hdl.handle.net/11441/79585This paper discusses design considerations for cascade Sigma-Delta Modulators (ΣΔMs) included in multistandard wireless receivers. Four different standards are covered: GSM, Bluetooth, UMTS, and WLAN. A top-down design methodology is proposed to find out the optimum modulator architecture in terms of circuit complexity and reconfiguration parameters. Several reconfiguration strategies are adopted at both architecture- and circuit-level in order to adapt the modulator performance to the different standards requirements with adaptive power consumption. Time-domain behavioural simulations considering a 0.13μm CMOS implementation are shown to validate the presented approach.application/pdfengAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/conferenceObjectinfo:eu-repo/semantics/openAccess
