Abstract :
This paper describes the design and implementation of a reconfigurable low power 180-nm CMOS cascade Σ-Δ modulator for multi-standard wireless communication. Both architectural and circuital reconfiguration is used to adapt its performance to multi-standard applications. Post layout simulation reveals that the prototype achieves 86.82/54.88/66.51d B peak signal-to-(noise+distortion) ratio within bandwidth of 200 kHz/2 MHz/4 MHz respectively for GSM/RFID (UHF)/WCDMA standards under power consumption of 7.6/11.1/13.3 mW in 1.8 V supply.
