Abstract: A startup circuit includes an enhancement mode transistor with a drain coupled to a startup circuit input, a source coupled to a first node, and a gate coupled to a second node. The startup circuit includes a current limiting circuit that controls a current path between the second node and a startup circuit output node based on a current sense voltage signal representing a current through the enhancement mode transistor, and a voltage regulation circuit controls a voltage of the second node to regulate a startup circuit output voltage of the startup circuit output node.

Abstract: The present disclosure generally relates to a semiconductor device that includes a gate electrical contact that forms junctions with different energy barrier heights to a gate layer. In an example, a semiconductor device includes a semiconductor substrate, a drain electrical contact, a source electrical contact, a barrier layer, a gate layer, and a gate electrical contact. The drain and source electrical contacts are on the semiconductor substrate. The barrier layer is over a channel region of the semiconductor substrate between the drain and source electrical contacts. The gate layer is over the barrier layer. The gate layer includes first and second semiconductor portions. The gate electrical contact contacts the gate layer. The gate electrical contact includes first and second metal portions. The first and second metal portions form first and second junctions with the first and second semiconductor portions, respectively. The first and second junctions have different energy barrier heights.
