Architectures and Circuits for A/D and D/A Conversion in CMOS Integrated Systems for Telecom Applications

  • Jan Sevenhans

Emerging telecom systems such as ADSL, VDSL demand state—of—the—art high speed and high resolution A/D and D/A converters. Moreover, cost and power consumption issues require the use of specific A/D and D/A architectures to achieve the wanted resolution at the required speed for the minimum power. In the first part of this paper an overview is given of various A/D and D/A converter architectures used in Alcatel telecom systems over the past 15 years. Emphasis is placed on the evolution of A/D and D/A converters for today’s ADSL applications. Then design considerations for high speed and high resolution pipelined A/D converters for future VDSL technology will be addressed.
