Abstract
A sensor includes 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.
