Abstract: Test method of a vibrational MEMS structure wherein, a direct, variable modification voltage is applied to a resonance modification test structure having non-rectilinear electrodes, modifying the resonance frequency of the movable mass and the driving frequency. During the test, the movable mass is verified about stability and, if not stable, the vibrational MEMS structure is rejected.

Abstract: The system on chip includes a memory controller adapted to receive transactions containing transaction information defining an access to a memory, the memory controller being configured to store the transaction information in a command register, and to control the access to the memory from the content of the command register. The memory controller includes verification circuitry configured to determine the access to the memory depending on a comparison between the transaction information stored in the command register and a list of special information defining special transactions.

Abstract: A method of performing an authentication process to authenticate an electric motor unit includes establishing, by an external controller, secure encrypted communication with motor electronics of the electric motor unit, and sending, by the external controller, an authentication request to the motor electronics over the secure encrypted communication. The method further includes receiving, by the external controller, an authentication response from the motor electronics, verifying, by the external controller, a motor of the electronic motor unit as an authorized part based on the authentication response, and enabling control of the motor by the external controller only after successful authentication.

Abstract: Provided is a voltage level shifter that operates in sub-threshold voltages. The level shifter includes a level shifting stage. The level shifting stage receives a first signal from a first voltage domain and outputs a second signal to a second voltage domain. The level shifter includes a first auxiliary stage. In response to the first signal having a first voltage level corresponding to a first logical state and a first node of the level shifting stage having a supply voltage level, the first auxiliary stage sources current to a second node of the level shifting stage. Sourcing the current to the second node accelerates a transition of the first node to a reference voltage. The level shifting stage outputs a second signal to a second voltage domain.

Abstract: Semiconductor dice are arranged onto a first surface of a common electrically conductive substrate. The common electrically conductive substrate has a second surface opposite the first surface and includes substrate portions and elongated sacrificial connecting bars extending between adjacent substrate portions. Insulating material is coated on the second surface of the elongate sacrificial connecting bars. Solder material is grown on the second surface of the common electrically conductive substrate. The insulating material counters growth of the solder material on the second surface of the elongate sacrificial connecting bars. Singulated individual semiconductor devices are provided by cutting the common electrically conductive substrate along the length of the elongate sacrificial connecting bars having the insulating material coated on its second surface.

Abstract: A memory system disclosed herein features left and/or right memory banks, with left and/or right input/output (IO) blocks aligned with the memory banks for managing data input and output. A control section, situated between the left and right input/output blocks, oversees memory operations, receives control signals, and performs stuck-at testing. The control section includes fault detection logic designed to output a first logic value (e.g., logic low) if logic values at each of its external inputs are identical, but output a second logic value (e.g., logic high) if not. The fault detection logic is capable of detecting stuck-at faults in the external inputs by performing both stuck-at-0 and stuck-at-1 testing. If only stuck-at-0 or stuck-at-1 faults are detected, the fault detection logic can pinpoint those faults by iteratively changing input values at each of its external inputs and observing the output of the fault detection logic.

Abstract: An electronic device includes multiple integrated circuits, each containing a power transistor connected between an input voltage node and a load node, as well as a regulation circuit generating at least one sense current representing the output current of the power transistor. The regulation circuits modulate the output currents of their power transistors based on a value derived from the sense currents generated by the regulation circuits of other integrated circuits. This derived value can be based on an average of the sense currents generated by the regulation circuits or on one of the sense currents. In particular, the integrated circuits can be arranged in a daisy-chained relationship, allowing each regulation circuit to compare its sense current with the one from the immediately preceding circuit, except for the first regulation circuit, which compares its sense current with the last circuit's sense current in the chain.

Abstract: The present disclosure relates to device including first and second terminals connected to a bus, third and fourth terminals connected to power supply and reference potentials. A first transistor and a first resistor are in series between the first terminal and a first diode connected to the third terminal. A second resistor, a second transistor and a second diode are in series between the first and fourth terminals. A third transistor and a third resistor are in series between the first diode and the second terminal. A fourth resistor, a fourth transistor and a third diode are in series between the second and fourth terminals. At each consecutive transmission of a dominant bit and of a recessive bit, a circuit sets the transistors at the ON state during a time period starting with the recessive bit.

Abstract: In embodiments, a clock signal calibration circuit for communication transmitters includes a multiplexer that creates a combined output pattern from input data patterns in reaction to the clock signal's edges. It uses a calibration data pattern generator, which supplies two sequential patterns—the second being a shifted copy of the first—to the multiplexer. An averaging circuit then generates two averaged signals corresponding to these patterns. Duty cycle control circuitry corrects clock signal imbalances if these averaged signals are unequal, thus adjusting the duty cycle distortion to achieve an ideal 50% duty cycle.
