Patent ID: 7675367

Claim:
A design structure embodied in a machine readable medium used in a design process for an integrated circuit, the design structure of said circuit comprising: a phase-locked loop circuit that includes: a charge pump outputting a control signal during operation of said phase-locked loop circuit; a voltage controlled oscillator responsive to said control signal and to a tuning signal during operation of said phase-locked loop circuit; and an LC tank circuit configured to generate said tuning signal as a function of said control signal, said LC tank circuit including: control signal monitoring circuitry configured to automatically monitor said control signal and generate an output signal; a controller for automatically generating a band selection signal as a function of said output signal; band sliding circuitry for generating an output voltage in any one of a plurality of bands, said band sliding circuitry being configured to select said one of said plurality of bands as a function of said band selection signal; and band determining circuitry responsive to said output voltage so as to create said tuning signal.
