Abstract
This tutorial discusses power supply noise on LSIs.
First we discuss causes and effects of power supply noise. We show that the power supply impedance and rush current at the mode switching
of an LSI are the main causes of the power supply noise. Next we introduce some methods to suppress the power supply noise by using passive devices or active circuits. Then we introduce power supply impedance emulation techniques to eliminate overkills and underkills at volume production pre-shipping test.
To understand and control the power supply noise are one of the keys to enhace the reliability of LSI operations.
