Abstract: A parameter monitoring circuit includes a code generation circuit configured to generate a first code, to which a first offset is applied, and a second code, to which a second offset is applied; a parameter adjustment circuit configured to generate a first parameter and a second parameter by respectively applying the first code and the second code to a current parameter; a comparator circuit configured to generate a first comparison result and a second comparison result, the first comparison result indicating a comparison result between the first parameter and a reference parameter value, and the second comparison result indicating a comparison result between the second parameter and the reference parameter value; and a parameter error detection circuit configured to detect an error in the current parameter, based on the first comparison result and the second comparison result.
