Patent ID: 8037431

Claim:
A design structure embodied in a non-transitory machine readable medium used in a design process, the design structure comprising: an interleaved voltage-controlled oscillator (VCO), including a ring circuit comprising a series connection of main logic inverter gates; a plurality of delay elements connected in parallel with a selected sequence of the main logic inverter gates; wherein each delay element comprises a feedforward section, comprising controls for regulating signal transmission through feedforward elements responsive to one or more control voltages; and a proportional section, comprising controls for regulating signal transmission through at least one logic inverter gate; at least one temperature compensation circuit comprising a logic inverter gate in series connection with one or more field effect transistors, the field effect transistor responsive to a compensating voltage input that is proportional to a temperature; an electronic circuit in signal communication with the at least one temperature compensation circuit and configured to provide a voltage signal responsive to the temperature; an amplifier in connection with the electronic circuit to amplify the voltage signal; and a DC offset generator configured to adjust the voltage of the amplified voltage signal, thereby providing the compensating voltage input; wherein the design structure comprises a netlist describing the interleaved VCO.
