Claim Text:
1. A circuit, comprising: at least two LC voltage controlled oscillators (LCVCOs), wherein each LCVCO includes a switch configured to selectively turn on or off the each LCVCO, and at least one selected LCVCO of the at least two LCVCOs is configured to provide a differential LCVCO output having a voltage swing less than a full voltage swing; and a converter coupled to the at least two LCVCOs and configured to receive the differential LCVCO output, wherein the converter comprises a multiplexer coupled to a respective LCVCO output of each of the at least two LCVCOs, wherein the multiplexer is configured to provide an output signal with the full voltage swing, and wherein the multiplexer comprises a pair of PMOS transistors having diode connected gates.
