Power-Ground Plane Transient Impedance:  The concept of impedance is explored and analyzed in both the steady-state and transient modes.  Current flow in a power-ground plane structure is analyzed from a transmission line viewpoint.  Relationships for effective capacitance, inductance, and impedance are developed.  The validity of the analysis is valid from time equal zero to twice the delay time to the first decoupling capacitor.  A Spice simulation is used to determine peak voltage disturbance.
