Abstract
With the development of semiconductor technic, The high speed, high density, high power consumption, low voltage and high current propose whicti lead to more＇ serious problems arouse in power integrity（PI） in today＇ s high-speed circuits design. This paper introduces the main noise power integrity.关键词
