Session 10 overview / data converters: Nyquist-rate converters

Summary form only given. The demands placed on high-speed communication are steadily increasing as services such as cloud computing, video-on-demand, and ever increasing web access, call for higher date rates with dramatically improved energy efficiency. In particular, optical network data rates are now approaching 100Gb/s, wireless cellular base stations are processing wide-spectrum content for multi-standard support, and cable modems and medical-imaging systems are striving to achieve GHz bandwidths. In response to these challenges, new analog-to-digital converter (ADC) and digital-to-analog converter (DAC) architectures are being developed that dramatically increase conversion rates and conversion efficiency by leveraging advanced CMOS, SiGe technology, and clever circuit techniques.
