ResumenThis paper presents the implementation and experimental characterization of a reconfigurable ΣΔ modulator intended for multi-mode wireless receivers that is capable to perform the analog-to-digital conversion for GSM, Bluetooth, and UMTS standards. The ΣΔ modulator reconfigures its cascade topology and building blocks in order to adapt the performance to the diverse standard specifications with optimized power consumption. The prototype has been implemented in a 130-nm CMOS technology and features dynamic ranges of 86.7/81.0/63.3dB and peak signal-to-(noise+distortion) ratios of 74.0/68.4/52.8dB at 400ksps/2Msps/8Msps, respectively. The modulator power consumption is 25.2/25.0/44.5mW, of which 11.0/10.5/24.8 mW are dissipated in the analog circuitry.
