Abstract :
A 2-2 cascaded multi-standard DeltaSigma modulator achieves a OR of 88/79/67dB in EDGE/UMTS/WLAN mode, respectively. With a high linearity of -92dB THD and 34dBm IIP3 for EDGE, this ADC is suitable for wireless applications. Implemented in 0.13 mum CMOS and occupying 0.4mm2, the modulator covers 0.1-to-10MHz signal bandwidth with scalable power consumption between 2.9 and 20.5mW from a 1.2V supply.
