  • Method and apparatus for automatically generating a phase lock loop (PLL)
    Patent number: 6704908
    Abstract: A method that automatically generates a design for an analog phase lock loop (PLL) core in response to a desired clock frequency.
    Type: Grant
    Filed: November 6, 2000
    Date of Patent: March 9, 2004
    Assignee: Amadala Limited
    Inventors: John Horan, John Ryan, Ciaran Cahill, Steven Dunphy, Mark Smyth, Kay Hearne, Niall O'Donovan, Tholom Kiely
  • Method and apparatus for level shifting approach with symmetrical resulting waveform
    Patent number: 6512407
    Abstract: A method is described that level shifts a differential signal to produce a first signal and level shifts the logical inverse of the differential signal to produce a second signal that is the logical inverse of the first signal. The method then inverts the first signal and inverts the second signal. The method then inverts the first signal and the inverted second signal together and inverts the second signal and the inverted first signal together.
