Patent ID: 7958469

Claim:
A system comprising: a non-transitory computer readable medium comprising a design structure for implementing a machine executable representation of an integrated circuit; and a computing device that executes instructions that cause the computer device to retrieve the design structure from the non-transitory computer readable medium and process the design structure to generate: a first design structure element representing a phase frequency detector; a second design structure element representing a charge pump coupled to the phase frequency detector; a third design structure element representing a filter coupled to the charge pump, the filter comprising a resistor; a fourth design structure element representing an oscillator coupled to the filter; and a fifth design structure element representing a feed-forward path coupled to the phase frequency detector and the oscillator, wherein the feed-forward path, in the representation of the integrated circuit, is a first connection that directly couples an output of the phase frequency detector to a first input of the oscillator and is parallel to a second connection between the output of the phase frequency detector and a second input of the oscillator, wherein the second connection, in the representation of the integrated circuit, comprises the charge pump and the filter.
