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.
Claims20
A method for monitoring a data converter, the method comprising:
- 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.
A device for data conversion, comprising:
- a data converter;
- a test signal circuit configured to determine a multiplicity of time-associated linearity parameters that describe a linearity of the data converter, at a multiplicity of different times;
- and
- a monitoring circuit configured to determine 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.
