1. A device, comprising:

  • a power supply input configured to provide a power supply signal;

    the first path configured to receive a clock signal and the power supply signal, the first path comprising;

    a first output;

    a first driver configured to accept the clock signal and modulate the power supply signal to generate, on the first output, a first oscillating power signal based on the clock signal;

    the second path configured to receive the clock signal and the power supply signal, the second path comprising;

    a second output;

    a delay element configured to phase shift the clock signal by an angle to generate a shifted clock signal; and

    a second driver configured to accept the shifted clock signal and modulate the power supply signal to generate, on the second output, a second oscillating power signal phase shifted by the angle with respect to the first oscillating power signal; and

    a transmission circuit coupled to the first output and second output and configured to transmit a wireless power signal based on a combination of the first and second oscillating power signals.
