Oversampled data converters are becoming increasingly popular
for high-precision data conversion. There have been many
publications on oversampled analog-to-digital (A/D) converters but
relatively few on oversampled digital-to-analog (D/A) converters.
In this thesis, issues concerning the analysis and design of the
oversampled D/A converters are addressed. Simulation tools and
analytical methods are discussed. A novel dual-quantization
technique for achieving high-precision D/A conversion is
proposed. A design example is presented to demonstrate that in
many aspects the proposed technique is superior to existing
techniques.
The thesis is divided into four chapters. Chapter 1 is an
introduction to the general concepts of Nyquist-rate and
oversampled data converters. Chapter 2 describes some building
blocks to be used in oversampled D/A converters and gives both
theoretical and simulation methods for analzying them. Chapter 3
describes the proposed dual-quantization D/A converters,
including the structure, the associated design issues and an
example to verify the validity of this technique. Finally, Chapter 4
summarizes the properties of the simulated system and proposes
some future research work. / Graduation date: 1992
