An adpative ΣΔ modulator for multi-standard hand-held wireless devices

This paper describes the design and experimental characterization of a 130-nm CMOS cascade ΣΔ modulator intended for multi-standard wireless telecom systems. Both architectural- and circuital-level reconfiguration strategies are incorporated in the chip in order to adapt its performance to different...
