Abstract
For high-speed internet access, high-performance analog front-ends are needed, and data converters are one of the crucial building blocks in these bent-ends. In this article we will report on the modeling and design of a D/A conversion interface for a DMT (discrete multi tone)-based ADSL system that could be integrated into a complete CMOS analog front-end. We will discuss the DMT transmit spectrum and its impacts on data converters, we will focus on modeling and simulating of the whole D/A interface, and we will describe a test chip implemented in a 0.6 μm CMOS process.
