摘要

提出了A /spl Sigma//spl Delta/调制器拓扑结构，通过修改环中量化器的传递函数实现高线性度。它适用于模数转换器和模数转换器。由于不需要随机噪声源，因此在A-D情况下获得了特殊的实现优势。实验结果表明，与传统的量化器抖动相比，该方案具有优良的动态范围特性。

A sigma-delta modulator topology with high linearity

A /spl Sigma//spl Delta/ modulator topology is presented which achieves high linearity by modifying the transfer function of the quantizer in the loop. It is applicable to both A-D and D-A converters. Particular implementation advantages are gained in the A-D case because no random noise source is required. Results are presented which show also that, in comparison to conventional quantizer dithering, the scheme has excellent dynamic range properties.
