Abstract: A modified power converter circuit utilizes an RLC circuit tuned to the frequency of any instability in the power converter circuit in order to remove the instability in the circuit output. In one embodiment, a pair of RLC circuits are connected in parallel across the input capacitor and output capacitor of the power circuit topology, respectively. The capacitor and inductor of each RLC circuit act as filters having a period with the same value as the instability created by interaction of the respective input or output capacitor with the isolation transformer inductance and expose the resistor within each the RLC circuit to only the frequency of instability.

Abstract: The invention relates generally to a method of power supply noise and signal integrity analysis for creating frequency-dependent electrical models particularly related to microelectronic packages. The method discloses creation of equivalent circuits for geometries encountered in a typical chip package, including how to partition the geometry into cells which are less then 1/20 the minimum wavelength (?) in size, and how to handle signal and power supply vias, signal wires, and power planes. The method also instructs how to assign values to each of the inductors, capacitors, resistors, and transmission lines in each equivalent circuit. The method further provides modeling of only those interactions which occur between adjacent cells.

Abstract: The present invention relates to an apparatus and method for enhancing the differential signaling speed performance of a PCI bus within a data processing system. In particular it involves the connectors employed with PCI bus architecture. The present invention involves providing improved connectors employed in a PCI bus architecture. These are Split Pin and Split Via connectors which provide significantly higher frequency and higher frequency capability to the board level.
