Abstract
Various aspects of the technology provide for a converter circuit such as a dc-dc voltage converter or buck converter. The circuit includes a enhancement mode control Field Effect Transistor (FET) fabricated using gallium arsenide and an depletion mode sync FET fabricated using gallium arsenide. A drain of the sync FET may be coupled to a source of the control FET and an inductor may be coupled to the source of the control FET and the drain of the sync FET.
