Abstract— In this paper first the traditional digital to analog conversion is discussed with circuit analysis. The concepts like propagation delay, inertial delay, step size are discussed. In the later part, the fuzzy logic circuit interface between digital to analog convertor is examined with the help of the latest paper on fuzzy interface. It is shown that the digital to analog conversion process is better carried out if represented by fuzzy logic interface between digital to analog interface. 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.
