摘要

本文将三角近似法和非线性逼近法相结合

提出了一种高压缩比的设计方案.并对该设计方案进行了详细的理论分析和参数优化

在16 bit的QDDFS系统中

压缩比达到了655.36∶1

并且无失真动态范围(SFDR)优于96dBc

最后给出了本方案的详细结构.

Abstract

Based on the principle of trigonometric approximation and non-liner approach

a new QDDFS Architecture with high compression ratio is presented.Its design principle has been analyzed theoretically and all the parameters have also been optimized in Matlab.A high compression ratio of 655.36 is achieved at 96 dBc in a 16bit system.Finally the whole architecture for proposed scheme is given.
