A/D and D/A converters in a mixed-mode CNN

Abstract

In this paper A/D and D/A converters in a mixed-mode cellular neural network (CNN) are analyzed. The choice of A/D converter type is discussed and design characteristics associated with A/D converter design for a mixed-mode CNN are overviewed. A current mode successive approximation type A/D converter suitable for use in a mixed-mode CNN cell is shown. A current mode D/A converter is also shown in block level.
