A New Method of Applying High Levels of Dither to Delta-Sigma Modulators

Document Thumbnail

This paper presents a new a new method of applying high levels of dither to Sigma-Delta Modulators. In particular, it clarifies the position of the overload point in one-bit Sigma-Delta Modulation systems and presents several overload control methods with comparisons of their efficacy. It then goes on to examine the problem of applying dither to one-bit systems and describes a new approach for applying high levels of dither. It also examines the effect of different dither probability density distributions and shows that simple bi-level dither can be effective at lower levels than other probability density distributions. It presents results, which show that dither can be applied at a high enough level to be effective in one-bit Sigma-Delta Modulation systems.
