ADC的结构方案概述

Introduction of the structures of ADC

本文介绍了并行结构、流水线结构、SAR结构和sigma-delta结构四种体系ADC的设计技术和优缺点。不同的应用中,关注的ADC指标不同,所以要在性能、功耗和成本之间折衷考量,选取最合适的技术方案。

Four different ADC structures such as flash type、pipeline type、SAR type and sigma-delta type are discussed. As to a specific application, trading-off between performance、power and cost is necessary to get a optimal solution.
