Design and Implementation of Sigma-Delta Converter in Oversampling frequency (English)
Abstract [en]

Nowadays, Sigma-Delta analog-to-digital converters have been widely used in the technology of analog-to-digital conversion. It depends on the merits that the approach of Sigma-Delta has. The signal converted by oversampling is precise and well-suited in signal processing systems.This thesis mainly focuses on the principles and simulations of fundamental first-order Sigma-Delta converter, and some brief introductions about other Sigma-Delta converters.The main researches of this thesis are as follows:

(1)This thesis shows not only the path about development of technology of different ADCs, but also the features and principles of these ADCs and their structures.

(2)The thesis discusses how the technologies of oversampling and noise shaping are used in Sigma-Delta analog-to-digital conversion.

(3)Illustrate different orders Sigma-Delta converters in different bits and their advantages and disadvantages, respectively.

(4)The simulation is given in Matlab(Simulink). Typical first-order SigmaDelta converter is simulated with additional noise which will impact the input signal when implement.
