A New Analog Input Topology for Extreme Dynamic Range Analog to Digital Conversion
The purpose of this paper is to introduce a novel form of input topology for the analogue inputs of oversampled Analogue to Digital converters. This new topology, when used with existing components, can achieve a dynamic range of 27 linear bits but has the potential to achieve even more if suitable technology can be developed. The paper analyzes the current limitations of existing topologies, presents the new topology, and shows how it can achieve much higher dynamic ranges. The optimal application of the topology and means of extending it for higher dynamic ranges is also discussed.
