Fuzzy-logic digital-analogue interfaces for accurate mixed-signal simulation

A new approach to mixed-signal circuit interfacing based on fuzzy logic models is presented. Due to their continuous rather than discrete character, fuzzy logic models offer a significant improvement compared with the classical D-A interface models. Fuzzy logic D-A interfaces can represent the boundary between the digital and analogue worlds accurately without a significant loss of computational efficiency. The potential of mixed-signal interfacing based on fuzzy logic is demonstrated by an example of spike propagation from the digital to analogue world. A model of inertial propagation delay and non-linear DC gain suitable for fuzzy logic gates is also suggested.
