Claim Text:
1. An apparatus comprising: transceiver circuitry usable to communicate a first wireless communication signal and a second wireless communication signal, wherein the first wireless communication signal complies with a first wireless communication standard, and wherein the second wireless communication signal complies with a second wireless communication standard; and a local oscillator that generates a local oscillator signal that is supplied to the transceiver circuitry, wherein the local oscillator comprises a Phase-Locked Loop (PLL) that includes a digitally programmable analog loop filter, and a digitally programmable Voltage-Controlled Oscillator (VCO) comprising a VCO and a digitally programmable VCO supply voltage circuit that draws power from a first supply voltage conductor and supplies a first regulated voltage to the VCO when the transceiver circuitry is communicating the first wireless communication signal, wherein the digitally programmable VCO supply voltage circuit draws power from a second supply voltage conductor and supplies a second regulated voltage to the VCO when the transceiver circuitry is communicating the second wireless communication signal.
