Oversampled CD-Quality D/A Converter for Integration on a 3D Graphics Controller IC

EECS 247, Spring 1997, UC Berkeley With the increasing popularity of multimedia PC’s and particularly multimedia laptop computers, there is an increasing need for high performance audio and video in the system. This paper reports on a stereo CD-quality D/A converter that has been developed for integration with a 3D graphics controller IC to help reduce the size and power of the multimedia subsystem. Because of the goal of integrating with the high speed graphics system, this D/A was designed to operate as in the digital domain as long as possible to maintain signal quality despite noise from the graphics system.
