Abstract

This paper demonstrates a power supply noise reduction using stubs. A quarter-length stub attached to the power supply line of an LSI chip works as a band-eliminate filter, and suppresses the power supply noise of the designed frequency. Preliminary experiments show that 90% of the designed frequency noise component is suppressed when off-chip stubs are attached to a power supply pin of a 1.15GHz operating LSI. The results show the possibility of the stub on-chip integration when the operating frequency of LSIs becomes higher and the stub length becomes shorter.
