1. A power amplifier comprising:

  • a first switching device connected between a first supply voltage and a first output node;

    a second switching device connected between a second supply voltage and a second output node;

    an inductance coupled between the first and second output nodes; and

    a preamplifier connected to the power amplifier, the preamplifier further comprising;

    a third switching device connected between said first supply voltage and a third node and coupled to the input to the first switching device;

    a fourth switching device connected between said second supply voltage and a fourth node and coupled to the input to the second switching device; and

    a second inductor coupled between the third and fourth nodes.
