A MATLAB toolbox synthesizing reconfigurable delta-sigma modulators for multi-standard wireless applications

摘要

This paper presents a high-level synthesis MATLAB toolbox for reconfigurable delta-sigma analog-to-digital converters used in multi-standard wireless communication terminals. The main algorithm synthesizing the reconfigurable delta-sigma modulators finds an optimal discrete time architecture which can be reconfigured for different considered communication standards and predicts the parameters of the modulator to achieve the required resolution for different operation modes. Estimating the requirements of analog blocks, combined with power consumption evaluation and extracting an area factor for different delta-sigma modulator architectures makes the proposed toolbox an advantageous alternative for reconfigurable delta-sigma modulator synthesis. As verification, the toolbox is used to verify some of the reconfigurable analog to digital converter (ADC) chips proposed and made for multi-standard wireless applications.
