Abstract

A current source layout arrangement for a current-mode D/A converter is disclosed. The D/A converter has a plurality of large current sources and a plurality of small current sources. Each large current source has a plurality of unit current sources, and the large current sources are divided into a plurality of groups, each consisting of two large current sources, for being symmetrically arranged. The unit current sources of two large current sources in one group are interlacingly interposed. Each small current source has at least one current source unit. The unit current sources of the small current sources are diagonally inserted into the arrangement of the unit current sources of the large current sources.
