Reconfiguration of Cascade ΣΔ Modulators for Multistandard GSM/Bluetooth/UIMTS/WLAN Transceivers

This paper presents design considerations for cascade Sigma-Delta Modulators (ΣΔMs) included in multi-standard wireless transceivers. 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...
