Structure for interleaved voltage controlled oscillator
First Claim
1. 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.
