  • Patent number: 8558626
    Abstract: An integrated circuit comprising oscillator circuitry is arranged to generate a clock signal for functional logic module of the integrated circuit. The oscillator circuitry comprises a plurality of propagation paths, and is arranged to apply a transition signal to inputs of the plurality of propagation paths, and to cause the output clock signal to transition based on a propagation of the transition signal through a determined set of the propagation paths.

  • Patent number: 8171336
    Abstract: A method for protecting a secured real time clock module, the method includes: locking multiple input ports of the secured real time clock module if the multiple input ports of the secured real time clock module are idle during at least a first duration; unlocking the multiple input ports of the secured real time clock module if a predefined high frequency code is received over a control input port of the secured real time clock module; and providing a secured real time clock signal when the multiple input ports of the secured real time clock module are locked and when the multiple input ports of the secured real time clock module are unlocked; wherein changes in a supply voltage results in a supply voltage induced changes of an input signal provided to an input port of the secured real time clock module; wherein a maximal frequency of the supply voltage induced changes of the input signal is lower than the high frequency of the predefined high frequency code.

  • Patent number: 7965119
    Abstract: A method and device for managing metastable signals. The device includes: a first latch and a second latch, a multiple switching point circuit, connected between an output node of the first latch and an input node of the second latch, wherein the multiple switching point circuit includes at least one pull up transistor and at least one pull down transistor that are selectively activated in response to a feedback signal provided from the second latch and in response to a an output signal of the first latch such as to define at least a low switching point that is lower than a high switching point of the multiple-switching point circuit; wherein a switching point of an inverter within the first latch is between the high and low switching points.
