摘要： A phase-locked loop having a phase detector for receiving a feedback signal and an input clock signal having an input clock frequency. The phase detector outputs or produces a phase error signal indicative of a comparison between the input clock signal and the feedback signal. The phase-locked loop also has a loop filter coupled to the phase detector to receive the phase error signal and to output an error correction signal which includes an error correction frequency having a value ranging from about [input clock frequency−(input clock frequency×about 0.00015)] to about [input clock frequency+(input clock frequency×about 0.00015)]. A voltage controlled oscillator is coupled to the loop filter for receiving the error correction signal and to generate an output signal of the phase-locked loop which is indicative of the feedback signal. A method for operating a phase-locked loop circuit is provided along with a filter circuitry for a phase-locked loop and a method for filtering a phase error signal.

摘要： A system and method for dynamically managing groups of power supplies for a computer system has a plurality of first circuits, each of the first circuits responsive to an electrical condition of each of the plurality of power sources. A second circuit is coupled to the plurality of first circuits, and is responsive to the plurality of first circuits. The second circuit identifies a state associated with any one of the plurality of power supplies. A third circuit is coupled and responsive to the second circuit. The third circuit communicates the states of the plurality of power supplies to a user.
