Broadband communication circuits in pure digital deep sub-micron CMOS

This paper discusses the future integration of analog broadband communication circuits in pure digital sub-micron CMOS technology by choosing cable modem and set-top box integration as application examples. System partitioning is discussed first to assess what will be integrated in CMOS technology, and then circuit-level problems are discussed by focusing on A-to-D converter (ADC) and D-to-A converter (DAC) designs.
