Robust clock generation system

Abstract

In this paper, the generation of time signals in a network node based on the weighting of phases from two master signals is studied. A discussion about the stability of such a system is conducted with techniques of multi-variable robust control. Designing compensators by using multi-variable linear quadratic gaussian (LQG) and loop transfer recovery (LTR) robust control techniques seems to improve the response of the whole clock generation process, even in the presence of parasitic poles.
