Abstract

This brief article presents the architecture and the implementation of a converter of analog signals into discrete signals of three levels, asynchronous, with sample frequency in the gigahertz band. To make possible the implementation of this converter, it was projected and also implemented an analog signals processor that functions stabilized round an inflection point, in substitution to the operational amplifiers used in the first version of the converter and that allowed to work with high gain and slew-rate. This processor is also described in this article.

Keywords
