  • Methods, apparatuses and systems for data conversion
    Patent number: 11635314
    Abstract: In accordance with an embodiment, a method for monitoring a data converter configured to convert data using a calibration determined by a calibration data record includes calibrating the data converter in order to determine a corresponding multiplicity of time associated calibration data records at a multiplicity of different times; and determining a state of the data converter based on comparing at least one of the multiplicity of time associated calibration data records with a comparison data record.
    Type: Grant
    Filed: May 29, 2019
    Date of Patent: April 25, 2023
    Assignee: Infineon Technologies AG
    Inventors: Peter Bogner, Andrea Cristofoli, Michael Kropfitsch, Jochen O. Schrattenecker
  • Methods, devices and systems for data conversion
    Patent number: 10771087
    Abstract: In accordance with an embodiment, a method of monitoring a data converter includes determining a multiplicity of time-associated linearity parameters that describe a linearity of the data converter at a multiplicity of different times, and determining a state of the data converter based on comparing at least one linearity parameter of the multiplicity of time-associated linearity parameters with a comparison parameter.
