Publication number: 20070013350Abstract: Disclosed is a power regulator for providing precisely regulated power to a microelectronic device such as a microprocessor. Improved power regulation is accomplished by optimizing the power efficiency of the power regulator. In particular, in a multiphase system, the number of active phases is increased or decreased to achieve optimum power efficiency. The multiphase voltage regulator adapts the operating mode to maximize efficiency as the load current demand of the load device changes by adjusting the number of active phases to maximize efficiency. The total value of current provided by the regulator and the total number of active phases is determined, the total number of active phases is compared with the number of active phases required to provide the total value of current at maximum efficiency; and the number of active phases is adjusted to provide the total value of current at maximum efficiency.Type: ApplicationFiled: July 3, 2006Publication date: January 18, 2007Inventors: Benjamim Tang, Robert Carroll, Nicholas Steffen, Richard Pierson

Publication number: 20060186543Abstract: A mask layer is applied to a surface of a semiconductor structure or a seed layer deposited on the surface. The mask layer has a submicron width opening with a high aspect ratio that exposes a portion of the surface or seed layer. Conductive material is conformed to the opening, for example by plating, to form a first contact on the surface or seed layer. The mask and the top layer of the semiconductor structure, except for the portion under the first contact, are removed to expose a second layer of the semiconductor structure. An insulating layer is formed along the sidewalls of the first contact and the top layer of the semiconductor structure beneath the first contact. A mask is then applied to the second layer and a second contact is formed by selectively depositing metal only on the portion of the second layer exposed by the opening.Type: ApplicationFiled: February 23, 2005Publication date: August 24, 2006Inventors: Petra Rowell, Miguel Urteaga, Richard Pierson, Berinder Brar

Publication number: 20060152205Abstract: Disclosed is a multi-phase pulse width modulated voltage regulator and method in which transient voltage excursions or deviations that exceed the load line voltage by more than a pre-determined amount are detected by an ATR circuit and a correction signal is applied. The correction signal is in the form of asynchronous pulses and the number of such pulses is a function of the magnitude of the voltage excursion as determined by the number of thresholds that are exceeded. Also disclosed is an adaptive voltage positioning (AVP) circuit and method for early detection of a transient event by sensing voltage changes at the load and adjusting the target voltage with pre-determined current values prior to the time that ATR event changes in the current at the load are detected. The AVP load line is pre-positioned for more precise current control. Also disclosed is an adaptive filter with adjustable frequency characteristics in response to an ATR event. Also disclosed is a pulse limiting circuit.Type: ApplicationFiled: December 19, 2005Publication date: July 13, 2006Inventors: Benjamim Tang, Robert Carroll, Scott Southwell, Kenneth Ostrom, Richard Pierson
