  • Patent number: 11428702
    Abstract: Reducing a sensitivity of an electromechanical sensor is presented herein. The electromechanical sensor comprises a sensitivity with respect to a variation of a mechanical-to-electrical gain of a sense element of the electromechanical sensor; and a voltage-to-voltage converter component that minimizes the sensitivity by coupling, via a defined feedback capacitance, a positive feedback voltage to a sense electrode of the sense element—the sense element electrically coupled to an input of the voltage-to-voltage converter component. In one example, the voltage-to-voltage converter component minimizes the sensitivity by maintaining, via the defined feedback capacitance, a constant charge at the sense electrode. In another example, the electromechanical sensor comprises a capacitive sense element comprising a first node comprising the sense electrode. Further, a bias voltage component can apply a bias voltage to a second node of the electromechanical sensor.

  • Patent number: 11431332
    Abstract: A gate drive circuit includes a driver for driving a gate of a switching element, a peak voltage detector, and a drive capacity calculator. The peak voltage detector detects a peak voltage at a main terminal of the switching element when the switching element is OFF. The drive capacity calculator calculates a voltage difference value between the detected peak voltage and an allowable voltage value at the main terminal of the switching element, where the allowable voltage is based on the specifications of the switching element. The drive capacity calculator changes a drive capacity of the driver to gradually decrease the difference between the detected peak voltage and the allowable voltage.

  • Patent number: 11429129
    Abstract: A multi-deck circuit arrangement including a first deck circuit having a negative supply terminal and a second deck having a positive supply terminal connected to the negative supply terminal. A single power supply provides a voltage across both the first and second decks. The total power consumption will be less than the prior art of having both deck circuits conventionally regulated. The supply rail connecting the second deck's positive supply terminal to the first deck's negative supply terminal may be regulated. In one embodiment, the rail voltage can be controlled to optimize deck circuit operation for speed and power and to avoid level shifters when interfacing to other circuits.

  • Patent number: 11418189
    Abstract: A driver circuit drives a high voltage I/O interface using stacked low voltage devices in the pull-up and pull-down portions of the driver. The transistor closest to the PAD in the pull-up portion receives a dynamically adjusted gate bias voltage adjusted based on the value of the data supplied to the output circuit and the transistor in the pull-down portion closest to the PAD receives the same dynamically adjusted gate bias voltage. The transistors closest to the power supply nodes receive gate voltages that are level shifted from the core voltage levels of the data supplied to the output circuit. The transistors in the middle of the pull-up and pull-down transistor stacks receive respective static gate voltages. The bias voltages are selected such that the gate-drain, source-drain, and gate-source voltages of the transistors in the output circuit do not exceed the voltage tolerance levels of the low voltage devices.
