Abstract
A power amplifier includes a first transistor and a first inductor disposed between the first transistor and a voltage source. A first node between the first transistor and the first inductor is an output node. The power amplifier further includes a second inductor disposed between the first transistor and ground The power amplifier further includes a third inductor coupled to a gate of the first transistor and configured as a first AC input. The power amplifier further includes a first phase conditioner inductively coupled to the second inductor and the third inductor and configured to set phases of AC signals across the first inductor and the second inductor in phase. The second inductor is configured to release energy into the first inductor to raise a voltage of the AC signal and raise a power output at the output node.
