dc.description 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 standard specifications with optimized power dissipation. Measurements show a correct operation for GSM/Bluetooth/WCDMA standards, featuring a dynamic range of 86.7/81.0/63.3dB and a peak signal-to-(noise+distortion) ratio of 74.0/68.4/52.8dB within 200kHz/1MHz/4MHz, respectively. The power consumption is 25.2/25.0/44.5mW, of which 11.0/10.5/24.8 are due to the analog part of the circuit.
