The delay locked circuit periodically performs the measurement to adjust a timing... Agent: Schwegman, Lundberg, Woessner & Kluth, P.A.

20070075764 - Level shifter system and method to minimize duty cycle error due to voltage differences across power domains: The present invention provides for a system comprising a first stable voltage module configured to receive a first power supply from a first power supply domain and to generate a first stable voltage in response to the received first power supply. A second stable voltage module is configured to receive... Agent: Ibm Corp. (wip) C/o Walder Intellectual Property Law, P.C.

20070075765 - Booster circuit: A booster circuit for boosting and outputting a voltage between a power supply potential line and a reference potential line using a capacitor connected between a boosted voltage output node and the reference potential line that includes a first switch for separating the capacitor from the boosted voltage output node...
