Hi all,
I want to design a digital delta-sigma DAC. It includes a pulse density
modulated module and RC low-pass filter.
The pulse density modulated module is a Delta-Sigma type (one adder and
one substractor). But why use Delta-Sigma type (i.e. how to understand
it)? Is there any good tutorial on digital Delta-Sigma?
I would recommend books from the authors Richard Schreier, Gabor C. Temes,
Steven R. Norsworthy and James C. Candy. Specifically the following books
cover almost all subjects from end to other:
R. Schreier, G. Temes, "Understanding Delta-Sigma Data Converters", 2004
http://www.amazon.com/gp/product/0471465852/103-2515440-5710236
Very good introduction to the principles, with many examples. A more
hands-on approach than many other books on the subject.
R. Schreier, G. Temes, S. Norsworthy "Delta Sigma Data Converters: Theory,
Design and Simulation", 1996
http://www.amazon.com/gp/product/0780310454/103-2515440-5710236
Very detailed and in-depth coverage with good theoretical background on most
subjects.
James C. Candy, Gabor C. Temes, "Oversampling Delta-Sigma Data Converters:
Theory, Design and Simulation", 1991
http://www.amazon.com/gp/product/0879422858/103-2515440-5710236
A collection of important scientific papers that covers the full (almost)
history of the development of this particular field of science. Very good
supplement for the two other books.
I have read several other books on the subject, but none of them have the
accuracy of these books. I would recommend not reading them cronologically,
but start with the newest one, and then progress to the older books if you
have a need for more background info or explanation of the theories.
