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.
Claims21
A method for monitoring a data converter configured to convert data using a calibration determined by a calibration data record, the method comprising:
- calibrating the data converter in order to determine a multiplicity of time associated calibration data records that describe a linearity of the data converter at a multiplicity of different times, wherein the data converter comprises an analog to digital converter or a digital to analog converter, and wherein the multiplicity of time associated calibration data records are associated with sub-components of the data converter, are stored in a memory, are configured to correct a non-linear response of an output signal of the data converter with respect to an applied input signal, and are separate from an output of the data converter;
- and
- determining a state of health of the data converter based on comparing a first calibration data record of the multiplicity of time associated calibration data records with a second calibration data record of the multiplicity of time associated calibration data records different from the first calibration data record, wherein the first calibration data record and the second calibration data record each describe the linearity of the data converter at different times from each other, and the state of health of the data converter indicates a life expectancy or a probability of failure of the data converter.
An apparatus for data conversion, comprising:
- a data converter configured to convert data using a calibration determined by a calibration data record, wherein the data converter comprises an analog to digital converter or a digital to analog converter, and;
- a calibration circuit configured to determine a multiplicity of time associated calibration data records that describe a linearity of the data converter at a multiplicity of different times, wherein the multiplicity of time associated calibration data records are associated with sub-components of the data converter, are stored in a memory, and are configured to correct a non-linear response of an output signal of the data converter with respect to an applied input signal, and are separate from an output of the data converter;
- and
- a monitoring circuit configured to determine a state of health of the data converter based on comparison of a first calibration data record of the multiplicity of time associated calibration data records with a second calibration data record of the multiplicity of time associated calibration data records different from the first calibration data record, wherein the first calibration data record and the second calibration data record each describe the linearity of the data converter at different times from each other, and the state of health of the data converter indicates a life expectancy or a probability of failure of the data converter.
