Mismatch and Dynamic Modeling of Current Sources in Current-Steering CMOS D/A Converters: An Extended Design Procedure
IEEE Transactions on Circuits and Systems I Fundamental Theory and Applications
This paper presents an improved modeling of the effect of random mismatch and current source transient switching behavior on the performance of current-steering CMOS digital-toanalog converters (DACs). The work considers two current source cell topologies, namely a simple cell and a cascoded cell, obtaining the relation of transistors design parameters to the static and dynamic models. On the one hand, a mismatching statistical analysis is applied to all the transistors of the current sourcedoi:10.1109/tcsi.2003.821287 fatcat:djam5qjuwvadhmxqywxnyaql5u
