Abstract:
A circuit includes at least two LC voltage controlled oscillators (LCVCOs). Each LCVCO includes a switch to selectively turn on or off the LCVCO. One selected LCVCO of the at least two LCVCOs is configured to provide a differential LCVCO output. A converter coupled to the at least two LCVCOs is configured to receive the differential LCVCO output and provide an output signal with a full voltage swing.
