Patent number: 10511303Abstract: The present disclosure presents a circuit, a method, and a system to drive a half-bridge switch using depletion (D) mode compound semiconductor (III-V) switching transistors for a DC-DC converter using at least one driver to drive the switches of the circuit. Also included is at least one charge pump electrically connected to a gate of the transistor, to maintain a voltage that holds the transistor in an off-state. The circuit includes AC coupling capacitors to level shift a voltage and realize fast transistor switching.Type: GrantFiled: September 26, 2017Date of Patent: December 17, 2019Assignee: Sarda Technologies, Inc.Inventors: Bogdan M. Duduman, Anthony G. P. Marini, William R. Richards, Jr., William E. Batchelor, Greg J. Miller, John K. Fogg

Publication number: 20190198442Abstract: Devices and methods are described for fabricating field effect transistors (FET) using compound semiconductor front end of line (FEOL) integrated with back end of line (BEOL) technologies for applications including power management and communications. Wafer-level FEOL processing with a minimum number of thin interconnects may be used to produce multiple chiplets, which are small, high current density functional building blocks. Chiplets may have tight source/drain finger pitch, high gate width per area, and minimum lateral current flow, to reduce resistance, FEOL process complexity, and cost. Panel-level BEOL processing may serve as an inexpensive extension of FEOL processes. BEOL may form multiple interconnect layers and via bars with progressively increasing thickness and cross section area. These BEOL interconnects and via bars connect together the parallel chiplets, handle lateral flow of high current and reduce electrical and thermal resistance the FETs to increase current carrying capacity of the FETs.Type: ApplicationFiled: December 20, 2018Publication date: June 27, 2019Inventor: William E.
