Researchers Submit Patent Application, "Integrated Circuit Device, Voltage Regulator Module and Method for Compensating a Voltage Signal", for Approval

By a News Reporter-Staff News Editor at Electronics Newsweekly -- From Washington, D.C., VerticalNews journalists report that a patent application by the inventors Priel, Michael (Netanya, IL); Fleshel, Leonid (Hertzelia, IL); Sofer, Sergey (Rishon Lezion, IL), filed on May 27, 2011, was made available online on July 3, 2014.

The patent's assignee is Freescale Semiconductor, Inc.

News editors obtained the following quote from the background information supplied by the inventors: "In the field of modern integrated circuit devices, and in particular in the field of integrated circuit devices for mobile or wireless applications, there is often a trade-off between reducing power consumption whilst increasing performance. In order to accommodate both requirements sufficiently, it is necessary to implement 'on-chip' power management. A critical part of such on-chip power management is the use of voltage regulators.

"In order to achieve a maximum operating frequency for an integrated circuit device, accurate voltage control is necessary, which requires high accuracy voltage regulators. By providing an on-chip regulator with good feedback of the relevant output voltage, a high degree of accuracy is typically achievable for the supplied voltage. However, inaccuracy in the output voltage can still occur, for example due to abrupt load changes that cause ripples in output voltage.

"One method for compensating for such high load changes is to implement a high comparator gain within the voltage regulator. However, such a high comparator gain impacts the system stability, in particular at low load current states, and thus is undesirable. Some known solutions propose implementing different regulator modes, whereby the different modes of the regulator provide, for example, better stability at lower load current states and better response times at higher load current states. However, in practice it is typically not possible to reliably distinguish between the states in a real system, thereby resulting in improper operation of the regulator."

As a supplement to the background information on this patent application, VerticalNews correspondents also obtained the inventors' summary information for this patent application: "The present invention provides an integrated circuit device, a voltage regulator module and a method for compensating a voltage signal output by a voltage supply module as described in the accompanying claims.

"Specific embodiments of the invention are set forth in the dependent claims.

"These and other aspects of the invention will be apparent from and elucidated with reference to the embodiments described hereinafter.
