This paper demonstrates a power supply noise reduction using on-board 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 87% of the designed frequency noise component is suppressed when stub patterns are written on a power supply area on...

As technology scales down, the effects of power supply noise and ground bounce are becoming significantly important. In the existing literature, it has been shown that excessive power supply noise can affect the path delay, while ground bounce is either neglected or assumed similar to power supply noise [1-2]. Our work performs a detailed study of combined and uncorrelated power supply noise an...

Harmonic problems are not new to electric utility and industrial power systems. In the past, most harmonicrelated problems were caused by large nonlinear loads such as arc furnaces. These types of problems have been effectively mitigated. However, due to the widespread proliferation of power electronic controlled devices nowadays, the problems caused by harmonics are of increasing importance. P...

This paper presents techniques to assist the power supply designer in accurately modeling and designing the control loop of a switchmode DC/DC power supply. The three major components of the power supply control loop (i.e., the power stage, the pulse width modulator and the error amplifier) are presented with power stage modeling being the focus of this presentation. The power stage is modeled ...
