Automatic placement for matched devices of analog circuits

摘要

It is time-consuming to obtain the matched devices by manual analysis and place them in hand for analog circuits of the mixed signal system. To achieve high performance, matched placement is a key point to layout design of analog circuits. In order to simplify layout design, it is necessary to realize the procedure automatically. In this paper, a method for automatic analog circuit placement is provided, as well as an efficient algorithm for the matched device groups. The experimental results verify the automatic placement algorithm of matched device groups.
