  • Patent number: 12040816
    Abstract: A number of unit cells of a digital-to-analog converter (DAC) may be simultaneously activated to generate an analog signal according to a decoded digital signal. However, while many unit cells may be generally the same, there may be variations in the gains associated with each unit cell (e.g., based on the locations of the activated unit cells within a unit cell array) amounting to a gain gradient that may cause error in the analog output. As such, a fill order may be set or selected to counter such variation by activating a particular arrangement of unit cells, as opposed to simply the number of unit cells, for a given digital signal. By filling the unit cell array from different sides, spatially and/or temporally, the gain gradient associated with the unit cells may be balanced to reduce error and increase the linearity of the DAC.

Responsive to a difference between the first number of errors and the second number of errors, the phase training update circuits adjusts a center phase position for the bit lane transmit phase offset of the selected bit lane.

  • Patent number: 11792051
    Abstract: A multi-channel digital isolator includes a digital isolator and an interlock circuit. The isolator includes a transmitter having a transmitter output, a receiver having a receiver input and a receiver output, an isolation barrier coupled between the transmitter output and the receiver input, and an output buffer having a buffer input and configured to output an isolated signal. The transmitter is configured to transmit an input signal across the isolation barrier. The interlock circuit has an interlock input coupled to the receiver output and an interlock output coupled to the buffer input. The interlock module is configured to prevent overlapping active states between the first isolated signal and a complementary isolated signal. In some implementations, the digital isolator also includes a dead-time insertion circuit.

  • Patent number: 11764614
    Abstract: An electrically conductive material configured having at least one opening of various unlimited geometries extending through its thickness is provided. The opening is designed to modify eddy currents that form within the surface of the material from interaction with magnetic fields that allow for wireless energy transfer therethrough. The opening may be configured as a cut-out, a slit or combination thereof that extends through the thickness of the electrically conductive material. The electrically conductive material is configured with the cut-out and/or slit pattern positioned adjacent to an antenna configured to receive or transmit electrical energy wirelessly through near-field magnetic coupling (NFMC). A magnetic field shielding material, such as a ferrite, may also be positioned adjacent to the antenna. Such magnetic shielding materials may be used to strategically block eddy currents from electrical components and circuitry located within a device.

  • Patent number: 11762075
    Abstract: An electronic device such as a wristwatch may be provided with a phased antenna array for conveying first signals at a first frequency between 10 GHz and 300 GHz and a non-millimeter wave antenna for conveying second signals at a second frequency below 10 GHz. The device may include conductive housing sidewalls and a display. Conductive structures in the display and the conductive housing sidewalls may define a slot element in the non-millimeter wave antenna. The phased antenna array may be mounted within the slot element, aligned with a spatial filter in the display, or aligned with a dielectric window in the conductive housing sidewalls. Control circuitry may process signals transmitted by the phased antenna array and a reflected version of the transmitted signals that has been received by the phased antenna array to detect a range between the device and an external object.
