1. An apparatus comprising:
a resonant amplifier circuit, wherein the resonant amplifier circuit comprises:
a first inductor having a first inductive input and a first inductive output;
a second inductor having a second inductive input and a second inductive output;
a first switch coupled, via a first terminal of the first switch, to the first inductive output; and
a second switch coupled, via a second terminal of the second switch, to the second inductive output, wherein the first switch and the second switch are driven out of phase based at least in part on a clock signal,
wherein the first inductor is configured to be resonant with a first capacitance coupled across the first terminal of the first switch and a second terminal of the first switch,
wherein the second inductor is configured to be resonant with a second capacitance coupled across a first terminal of the second switch and the second terminal of the second switch,
wherein the first inductive output of the first inductor is coupled to the first terminal of the first switch and a second terminal of the first capacitance, and
wherein the second inductive output of the second inductor is coupled to the second terminal of the second switch and a second terminal of the second capacitance;
an impedance matching circuit configured to enable an impedance match to a load coupled to an output of the apparatus; and
a direct current filtering circuit configured to at least enable blocking at least a portion of direct current from reaching the load coupled to the output of the apparatus.
