本文演示了一个电源噪声降低使用存根。附接到LSI芯片的电源线的四分之一长度短截线用作带阻滤波器，并且抑制设计频率的电源噪声。初步实验表明，当片外短截线附加到1.15GHz工作LSI的电源引脚时，设计的频率噪声分量被抑制了90%。结果表明，当LSI的工作频率变高，短截线长度变短时，短截线片上集成是可能的。
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.
