Abstract
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.
