Analogue-to-digital and digital-to-analogue conversion with memristive devices

A novel methodology is suggested to obtain a digital representation of analogue signals and to perform its back-conversion using memristive devices. In the proposed converters, the same memristive systems are used for two purposes: as elements performing conversion and elements storing the code. This approach to conversion is particularly relevant for interfacing analogue signals with memristive digital logic/computing circuits.
