Study of Analog-To-Digital Converters In Cmos Technologies

Exploring the Integration of High-Dynamic Range ADCs in CMOS Wireless Transceivers

Abstract

In wireless systems, the desiredchannel must be selected in the presence of strong adjacent-channelinterferers. This requires wideband analog-to-digital converters (ADC) that candigitize both the desired and adjacent-channel interferers, resulting inhigh-dynamic range (DR) requirements. Meanwhile, the advances in the CMOS pro­cess,combined with its economical advan­tages, is driving the integration of acomplete wireless transceiver in baseline CMOS. The demand for greaterthroughput leads to digital modulation schemes of greater com­plexity combinedwith a greater signal band.
