Performance Improvement of 18-bit ΣΔ A/D Convertor

Abstract

The research paper presents a simulation study to develop and improve the overall performance of sigma delta ($\Sigma\Delta$)A/D modulator, the circuit structure and technique used were explained and the processes of different parameters of $\Sigma\Delta$ modulator over the conventional modulator were explained clearly. Simulated results of the proposed $\Sigma\Delta$ system shows a good improvement in the spurious noise produced by the conventional A/D converter.
