Abstract

In this paper a link is made between dynamics and propagation in a chain of resistively coupled cells and the behavior of positive feedback comparators which are the primary blocks in analog to digital converters (ADC). It is pointed out that both behaviors can be explained with the same nonlinear dynamics. It turns out that an important property of the common unique cell is a two stable equilibria characteristic, inherent in some positive feedback systems. This characteristic is presented in the case of latched comparators. The dynamics of a comparator and a chain of comparators are also considered.
