Abstract:
Methods and apparatus for providing a local oscillator (LO) signal are disclosed. An example apparatus includes a circuit for providing the LO signal. The circuit includes a voltage controlled oscillator (VCO) that is configured to operate at a first supply voltage. The VCO is also configured to produce a VCO signal. The circuit also includes an LO generator that is coupled with the VCO so as to receive the VCO signal. In the example apparatus, the LO generator is configured to operate at a second supply voltage, where the second supply voltage is greater than the first supply voltage. Further, the LO generator includes one or more resistively loaded circuits for producing the LO signal from the VCO signal.
