Abstract
This paper describes a di/dt noise reduction method, which attaches stubs to the power line in LSI chips. A theoretical model of a lossy transmission line stub is investigated, and simulation results show that the stub can reduce 48% and 26% of the noise compared with the non stub-attached case, and de-coupling capacitor case, respectively, in a 2.5 GHz 1.8 V operation test circuit. It is also shown that this method will work more efficiently for further high frequency operation chips.
