摘要

提出了一种启发式搜索稳定高阶δ σ调制器的方法。在线性模型指导下的搜索发现，与经典滤波器设计技术相比，稳定的调制器具有更高的信噪比性能。所提出的设计方法既比经典设计更自动化，也可以加权，以指导对特殊目的设计的研究。提出了一种新的自适应调制器概念。

Using Heuristic Search To Find Stable High-Order Single-Bit Delta Sigma Modulators

A heuristic search for stable high-order delta sigma modulators is presented. Searches guided by the Linear Model found stable modulators with higher SNR performance compared to classical filter design techniques. The presented design approach is both more automatic than classical design and can also be weighted such to direct the search toward designs for special purpose. A novel adaptive modulator concept is also presented.
