1. A sensor comprising:
a first sensing element configured to sense a parameter and generate a first sensing element output signal indicative of the parameter;
a first front end element configured to receive the first sensing element output signal and to generate a first front end signal;
a second sensing element configured to sense the parameter and generate a second sensing element output signal indicative of the parameter;
a second front end element configured to receive the second sensing element output signal and to generate a second front end signal;
a difference block configured to receive the first and second front end signals and generate a difference signal indicative of a difference between the first and second front end signals;
an absolute value block configured to receive the difference signal and generate an absolute difference signal indicative of an absolute value of the difference signal; and
an offset comparator configured to compare the absolute difference signal to an offset threshold to detect whether a difference between an offset associated with the first front end signal and an offset associated with the second front end signal is within a predetermined tolerance.
