Patents by Inventor Bruce KAUFFMANN

Bruce KAUFFMANN has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11868193
    Abstract: A system includes a controller configured to receive a signal indicating whether a droop event has occurred. The system also includes a plurality of delay elements where each delay element of the plurality of delay elements responsive to a signal from the controller receives an input signal and outputs an output signal that is a delayed version of the input signal. At least one delay element of the plurality of delay elements receives a clocking signal as its input signal. The system also includes a selector configured to select rising edges and falling edges of output signals from the plurality of delay elements to form a modified clocking signal. The modified clocking signal is a modified version of the clocking signal.

  • Publication number: 20160139656
    Abstract: Systems and methods are provided for reducing surge current in power gated designs. In one aspect, a storage capacitor supplies a portion of the current used to power up a circuit. The storage capacitor may be charged from a power supply or other source. When the circuit is to be powered up, the circuit is connected to the power supply and the storage capacitor. As a result, current is supplied to the circuit from the power supply and the storage capacitor to power up the circuit. Because a portion of the current used to power up the circuit is supplied from the storage capacitor, the amount of current needed from the power supply to power up the circuit can be reduced, thereby reducing current surge through the power supply. The storage capacitor may be shared by multiple circuits.
