ABSTRACT:
In a method of the present invention, performance characteristics of a printed circuit board are analyzed. The printed circuit board, bypass components and an applied stimulus are modeled. Each of the bypass components includes a capacitor and a resistor in series with each other. Alternatively, a second capacitor is coupled in parallel to the above capacitor and resistor. A simulation of the circuit model is then performed. In this embodiment of the invention, the simulation is responsive to the stimulus as is performed over a range of bypass resistor values. In another embodiment of the invention, a printed circuit board is described with components and characteristics that reduce noise. Such a printed circuit board includes a power plane and a plurality of bypass components. Moreover, the plurality of bypass components include bypass capacitors and bypass resistors coupled in series between the positive power plane and the negative power plane.
