  • Publication number: 20180232005
    Abstract: Aspects include a method for generating a signal in response to an event. The method includes receiving, from a clock signal generator, a clock signal, wherein the clock signal has a fixed clock period. The method further includes receiving an indication of a pulse and, responsive to receiving the indication of the pulse, generating an output comprising a high voltage having a starting time and an ending time. The starting time is a first time when the indication of the asynchronous event is received, and the ending time is a second time at one fixed clocked period from the starting time.

  • Patent number: 10033270
    Abstract: An apparatus for providing a local reference voltage for a voltage regulator includes a reference capacitor configured to provide the local reference voltage, a charge pump configured to push current to, or pull current from, the reference capacitor according to one or more control inputs received by the charge pump, and a boosting circuit configured to add or subtract a discrete quantity of charge to the reference capacitor according to one or more boosting control signals. A boosting control circuit may be configured to disconnect a boosting capacitor from the reference capacitor during a first phase of a control cycle and connect the boosting capacitor to the reference capacitor during a second phase of the control cycle. The boosting capacitor may be pre-charged (to add charge) or discharged (to subtract charge) during the first phase of the control cycle. A corresponding method is also disclosed herein.
