  • Patent number: 12092664
    Abstract: One or more layout techniques may be used to balance a current sense circuit. The current sense circuit may include upstairs resistors for an amplifier which are formed of polysilicon material. The upstairs resistors may be arranged symmetrically about one or more stress gradients for improving an accuracy of the current sense circuit. The stress gradients may include stress gradients about an axis and stress gradients from a die edge.
    Type: Grant

  • Patent number: 12040758
    Abstract: An integrated circuit for measuring current while receiving wireless power is described. The integrated circuit measures a current across a resistor by an amplifier. A gain of the amplifier is based on a pair of matched upstairs resistors and a pair of matched downstairs resistors. The pair of matched upstairs resistors may include an offset in resistance. The integrated circuit includes a switch matrix with switches coupled between the integrated resistor and the pair of matched upstairs resistors. The offset for the pair of matched upstairs resistors may be measured by selectively controlling the switches.

  • Publication number: 20240003941
    Abstract: A structure is described which includes two amplifiers in parallel. A first amplifier is considered an always-on amplifier. The always on amplifier provides continual measurements of a current (Isns) across an integrated polysilicon resistor for one or more analog control loops. A second amplifier is considered a switched amplifier. The switched amplifier provides measurements of the current (Isns) for one or more digital control loops. The switched amplifier is switched by one or more switches for performing offset measurements with high accuracy.

  • Patent number: 11656188
    Abstract: Systems and methods are provided for scanning an item utilizing an X-ray scanner in order to facilitate a determination of whether the X-ray radiation penetrated through the entirety of the scanned item. Various embodiments comprise a conveying mechanism, an X-ray emitter, a detector, and an X-ray penetration grid (XPG). The XPG may comprise a radiopaque grid that may serve as a reference for determining whether radiation passes through the scanned item, the grid oriented such that the grid members are neither parallel nor perpendicular to the direction of travel. Such orientation may minimize or eliminate “ghosted” radiation signals included in a visual display of the radiation received by the detector. A scanned item may be oriented with the XPG such that radiation emitted by the X-ray emitter that passes through a portion of the scanned item must also pass through the XPG before being received by the detector.

  • Patent number: 10971954
    Abstract: Systems and methods for object detection are provided. The system includes at least a coil, a small signal generator, a small signal receiver, and a processor. The small signal generator includes a digital-to-analog converter circuit with programmable impedance. The small signal generator is configured to select an output impedance for the digital-to-analog circuit for capacitive sensing or radio-frequency identification (RFID) tag detection; generate a small signal according to the output impedance; and provide the small signal to the coil. The small signal receiver receives the small signal and a response signal associated with the small signal and measures the response signal to generate a measured signal. The processor compares the measured signal with one or more reference signals and performs capacitive sensing and/or detect a RFID tag according to the comparison.

  • Patent number: 10862347
    Abstract: Systems and methods for object detection are provided. The system includes at least a coil, a main transmit inverter circuit, and one or more circuits. The one or more circuits are configured to generate a small signal, provide the small signal to the coil, receive a response signal, compare the response signal with one or more reference signals, and detect an object according to the comparison. The object is detected without providing a signal from the main transmit/receive inverter circuit to the coil.

  • Publication number: 20200144927
    Abstract: A dual-comparator rectifier circuit of a wireless power receiver includes a receive coil configured to generate a current in response to receiving power through electromagnetic waves from a wireless power transmitter and a bridge circuit. The bridge circuit includes four branches, and one node of each of the four branches is coupled to one of a first node or a second node of the receive coil. A first branch and a second branch of the four branches are coupled to the first node and the second node of the receive coil and include a first circuit and a second circuit, respectively. The first circuit includes a first comparator and a first switch circuit and the second circuit includes a second comparator and a second switch circuit. The first circuit and the second circuit can set a dynamic turn-on threshold for the first switch circuit and the second switch circuit, respectively.
