1. A direct current-to-direct current (DC-DC) converter, comprising:
a first switching circuit comprising a first transistor coupled between a first capacitor and an input node, a second transistor coupled between the first capacitor and a second capacitor, a third transistor coupled between a first node and a third capacitor, and a fourth transistor coupled between the third capacitor and a ground node, the first node being between the second capacitor and the second transistor;
a second switching circuit comprising a fifth transistor coupled between the second capacitor and the third capacitor, a sixth transistor and a seventh transistor coupled between the first capacitor and the third capacitor, and an eighth transistor coupled between the first capacitor and the ground node;
a fourth capacitor coupled to a second node between the sixth transistor and the seventh transistor; and
an inductor-capacitor (LC) filter coupled to a third node, the third node coupling the first capacitor, the second transistor, and the eighth transistor.
