Symbolic techniques applied to switched-current ADCs synthesis

This paper discusses the use of symbolic methods applied to the design automation of SI data converters. The proposed approach is an extension of an already proved methodology, for the symbolic synthesis of linear and nonlinear data converters. This is performed by introducing SI characteristics in modified signal flow graph representation of conversion algorithms, including a new set of functional and electrical structures in the system library and, finally, defining an appropriate sizing mechanism for the new structures. The design process is here exemplified for a well known data conversion algorithm
