1. A receiver, comprising:

  • a local oscillator for supplying a signal;

    an amplifier coupled for receiving the signal and supplying first and second differential output signals, wherein the amplifier includes,a first transistor having a control terminal coupled for receiving a first reference voltage and a first current carrying terminal coupled for receiving the signal;

    a first inductor having a first terminal coupled to a second current carrying terminal of the first transistor for supplying the first differential output signal;

    a second transistor having a control terminal coupled for receiving a second reference voltage, a first current carrying terminal coupled to a second terminal of the first inductor, and a second current carrying terminal coupled for supplying the second differential output signala capacitor having a first terminal coupled to the first current carrying terminal of the first transistor and a second terminal coupled to the control terminal of the second transistor; and

    first and second mixers each having a first input for receiving a modulated signal and a second input coupled for receiving the first and second differential output signals generated by the amplifier.
