Comparative Analysis of Switching Schemes for 6-bit Arrays in Binary DACs

Abstract

This paper is devoted to switching schemes for binary DACs. At present, there are plenty of switching schemes compensating the systematic error influence. However, a lack of detailed simulation and comparison does not allow choosing the most effective one. In this paper, 12 switching schemes are simulated and compared. The Flower switching scheme is proposed. A detailed analysis both of switching schemes’ properties and of the correlation index usefulness is presented. A modification of the correlation index for the case of binary arrays is proposed.
