Simultaneous switch noise, or power/ground bounce noise, on the power and ground planes of high‐speed circuit packages is one of the main concerns of signal integrity or power integrity issues. A novel time‐domain approach is proposed to synthesize the broadband models of the resonance effect of power/ground planes. Either from measurements by time‐domain reflectrometry or simulations by the finite‐difference time‐domain method, the time‐domain step response of the planes is characterized with a pole‐residue representation obtained through the matrix pencil method. A new equivalent circuit models are then synthesized through the pole‐residue representations. The synthesized model can accurately predict the resonance behavior of power/ground planes over a wide frequency range. These models can be efficiently incorporated into the currently available circuit simulator such as HSPICE or Agilent ADS for the consideration of power/ground bouncing noise in high‐speed circuits. © 2007 Wiley Periodicals, Inc.
