Abstract

Sigma-Delta (σΔ) modulation is the only form of analogue-to-digital conversion which allows to achieve high bit resolution at relatively low costs. There is a lack of tools in academic and in industry that allow entry level engineers to familiarise with the concepts governing this conversion technique, especially for high orders, multibit and different architectures of σΔ modulators. The goal of this paper is to present a graphical toolbox [1], developed in Simulink and based on the behavioral model previously presented in [2] and available in [3], which allows to simulate and theoretically evaluate ten different architectures, continuous and discrete time as well as single-bit and multibit implementations of different orders of analog-to-digital Sigma-Delta modulators.
