A study of basic building blocks of analog-to-digital delta-sigma modulators

Creator:

Guo, Yuhua

Abstract:

In this thesis, a novel Direct-Charge-Transfer (DCT) integrator structure is proposed, which can settle much faster than regular switch-capacitor integrators. A new Spread-Spectrum Dynamic Element Matching (SS-DEM) algorithm is also introduced, which can effectively spread or shape the nonlinearity error of multi-bit DAC in the feedback path, thus improve the...

Generalized radix design techniques for low-power, low voltage pipelined and cyclic analog-digital converters

Creator:

Sharma, Vivek

Abstract:

This thesis proposes a novel technique for the design of pipelined and cyclic ADCs utilizing generalized radix gain stages. Several models have been proposed for the optimization of high performance pipelined ADCs by various researchers. This work builds upon them, using a simple but accurate model to estimate the optimal...

Masters Thesis
Noise optimization for low-voltage CMOS audio preamplifier systems

Creator:

Brown, Matthew Eugene

Abstract:

There is a large and growing market for portable consumer audio products with very small size. As the size of these products is reduced, the area occupied by batteries becomes significant and hence limits the number of batteries to one. In order to build such small products, high levels of...
