Symbolic synthesis of non-linear data converters

This paper discusses the use of symbolic methods applied to the design automation of non-linear data converters. The proposed approach is an extension of an already proved methodology, for the symbolic synthesis of linear data converters, by both introducing non-linear characteristics in a modified signal flow graph approach and reusing library functional blocks by an appropriate retargeting for the new design goals. The design process is here exemplified with recently proposed architectures for logarithmic data converters.
