Abstract:
1. A power amplifier comprising: a first transistor; a first inductor disposed between the first transistor and a voltage source, wherein a first node between the first transistor and the first inductor is a first output node; a second inductor disposed between the first transistor and ground; a third inductor coupled to a gate of the first transistor and configured as a first AC input; 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; a second transistor; a fourth inductor disposed between the second transistor and a ground, wherein a second node between the second transistor and the fourth inductor is a second output node; a fifth inductor disposed between the second transistor and the voltage source; a sixth inductor coupled to a gate of the second transistor and configured as a second AC input; and a second phase conditioner inductively coupled to the fifth inductor and the sixth inductor and configured to set phases of AC signals across the fourth inductor and the fifth inductor in phase.
