Abstract

Abstract:

This paper proposes a new method which aims at reducing big jitter caused by adjacent interconnection line crosstalk. Based on an analytical model of the interconnection payload, the method adaptively adjusts the signal drive strength according to the payload size to maintain the stability of communication delay, so as to effectively limit signal jitter. Compared with the drive mode of the buffer, under the condition of the same W/L of the driving buffer, the relative signal jitter decreases 29.6 percents when the length, wide and space of interconnection lines are 2mm, 0.4μm, 0.4μm, respectively, thus effectively improving the maximum operating frequency of long interconnects.

Key words: coupling, crosstalk, jitter, adaptive drive
