Placement Techniques of Element Parts for Unary DACs

This paper focuses on switching schemes in unary digital-to-analog converters. In some switching schemes, each weighting element is divided into several parts. In this work, a brief overview of techniques for a parts placement is presented. A simulation of several techniques shows the dependence of nonlinearity reduction from a parts number and a number of parts in a row and a column. Moreover, switching schemes with full parts distribution are analyzed in detail.
