ANALOG FRONT-END COMPENSATION

PROBLEM TO BE SOLVED: To provide techniques for compensating for various parasitic components such as leakage current and/or offset voltage in a transducer containing a sense element and associated analog front-end circuitry.SOLUTION: An apparatus may include a sense element that may measure a property such as pressure. The sense element may produce an output based on the measured property. Circuitry associated with the sense element may store a voltage that represents the output produced by the sense element. The circuitry may include, for example, a capacitor which may store the voltage. The stored voltage may include one or more parasitic components such as an offset voltage and/or voltage associated with leakage current. The circuitry may adjust the stored voltage to compensate for the parasitic components. The adjustment may occur over a series of phases of operation of the circuitry.
