  • Patent number: 11527953
    Abstract: A phase locked loop having a charge pump is described. The charge pump relies on close matching of FETs (Field Effect Transistor) electrical parameters to FETs in a current reference circuit. To achieve close matching of FET electrical performance, FEOL (Front End Of Line), comprising all FET shapes, of the current pump is identical in shapes and layout to the current reference circuit. BEOL (Back End Of Line) differs between the charge pump and the current reference circuit. The charge pump and the current reference circuit are arranged in a row. A shield circuit having FEOL shapes and layout identical to the current pump may be placed at each end of the row.

  • Patent number: 11475263
    Abstract: Aspects of the disclosure provide for automatically generating labels for sensor data. For instance, first sensor data for a vehicle may be identified. This first sensor data may have been captured by a first sensor of the vehicle at a first location during a first point in time and may be associated with a first label for an object. Second sensor data for the vehicle may be identified. The second sensor data may have been captured by a second sensor of the vehicle at a second location at a second point in time outside of the first point in time. The second location is different from the first location. A determination may be made as to whether the object is a static object. Based on the determination that the object is a static object, the first label may be used to automatically generate a second label for the second sensor data.

    Abstract: An automated system for translating source code written in one programming language into a different programming language utilizes a neural transformer with attention trained on semi-supervised data. The model is jointly pre-trained with a masked language model objective and an autoregressive objective on a large unsupervised source code corpus to learn to comprehend the syntactic structure and semantics of source code. The pre-trained model is then fine-tuned with a token-type prediction objective and an autoregressive objective on supervised translation tasks and data augmented tasks to learn to translate source code from one programming language into a different programming language.
