Abstract:
1. A method for detecting an error of an analog-to-digital converter configured to generate at least one digital output signal, which includes a plurality of output data bits, based on at least one analog input signal, comprising: generating, during an analog-to-digital conversion, a thermometer code which includes a quantity T of output data values; directly generating a first parity for actual values of the output data bits of the output signal; providing predicted values for the output data bits of the output signal, on the basis of the quantity T of output data values of the thermometer code; generating a second parity for the predicted values of the output data bits of the output signal, wherein the second parity is an inverse of the first parity in the case of error-free state of the analog-to-digital converter; and detecting an error for the analog-to-digital converter if both the first and second parities are identical.
