Abstract: Various embodiments of the present disclosure disclose improved silicon carbide (SiC) power devices and methods of fabrication of such devices. A SiC power device includes a semiconductor base material with a first side and a second side and a first metallic layer disposed on the first side of the semiconductor base material that forms ohmic contacts and Schottky contacts. The SiC power device may be fabricated by forming a first metallic layer on a first side of a semiconductor base material to form a Schottky contact, forming a second metallic layer over the first metallic layer to form a reflective barrier covering the Schottky contact, removing one or more portions of the second metallic layer to expose a first portion of the first metallic layer, and forming silicide portions on the first metallic layer to form ohmic contacts within the Schottky contact.

Abstract: According to an embodiment, a method for testing and repairing local memory in a hardware accelerator from a one-time programmable memory (OTP) is provided. The method includes asserting a grant signal, a loading of a first repair data for a sub-set of the local memory associated with a main-controller from a first partition of the OTP memory, communicating a status signal after completion of the loading indicating a completion of the loading, and de-asserting the grant signal in response to receiving the status signal.

Abstract: The present disclosure relates to a method for managing the deep sleep mode of an embedded system. In embodiments, the method includes determining a value of the electrical charge used, during a deep sleep mode of the system, for saving software-context data into a non-volatile memory of the system; determining a value of a current used, during a deep sleep mode of the system, for saving software-context data into a volatile memory of the system; determining, from the previously determined values, a threshold value defining a duration beyond which a power consumption caused by saving software-context data into the non-volatile memory is less than that into the volatile memory; saving the software-context data into the non-volatile or volatile memory according to the expected duration of deep sleep mode of the system.

Abstract: An inertial MEMS device includes an inertial element provided by a movable structure that is responsive to movement. The moveable structure is formed in a first structural layer of semiconductor material. A suspended structure extends above the movable structure at a distance therefrom. The suspended structure is formed in a second structural layer of semiconductor material and carries a piezoelectric structure. The suspended structure and the piezoelectric structure form a wake-up element that generates an activation signal in presence of vibrations or shocks. The inertial element and the wake-up element are contained in a chamber formed by a substrate and a cap, together with peripheral portions of the first and the second structural layers.

Abstract: A voltage regulator circuit includes an input configured to receive an input voltage, an output configured to produce a regulated output voltage, a pass element coupled between the input and the output, a bypass element coupled in parallel with the pass element, a feedback divider coupled between the output and a ground node, an error amplifier coupled between a control node of the pass element and the feedback divider, and a dropout transition control circuit coupled to the feedback divider configured to activate a dropout mode of the voltage regulator circuit by controlling a dropout transition at the output from the regulated output voltage to a dropout voltage level to limit inrush current. The feedback divider is configured to produce a feedback signal indicative of the output voltage. The error amplifier is configured to minimize the difference between a reference and the feedback signal.
