Application of Wavelets and Generalized Pencil-Of-Function Method for the
Extraction of Noise Current Spectrum and Simulation of Simultaneous Switching

Abstract
In high performance systems, the voltage fluctuation
noise caused by the simultaneous switching of circuits is
an important concern in relation to signal integrity and
radiated emission related issues. For proper design of the
Power Distribution System the noise current is required
as an input for the simulation of the simultaneous
switching noise. This paper proposes a measurement
based approach to estimate the noise current spectrum in
a functioning computer system. Its also discusses a
method for extracting the current signature needed to
simulate switching noise in the system. The proposed
approach is tested on a high speed functioning computer
system from Sun Microsystems. Using the current source
developed, simultaneous switching noise in the core
power distribution network of the system has been
simulated with good accuracy.
