  • Non-linear sensor temperature compensation using summed temperature compensation signals
    Patent number: 8081006
    Abstract: A sensor temperature compensation circuit that includes a sensor and non-linear temperature compensation circuit that compensates for non-linear temperature dependencies in offset and/or gain generated by the sensor. For instance, to at least partially compensate for offset temperature dependencies, a summer adds two offset compensation signals, the ratio of the second to the first being a function of temperature. The summed signal may then be multiplied by a function of temperature. The summed signal may then be used to provide the non-linear temperature compensation to the offset. Alternatively or in addition, to at least partially compensate for gain temperature dependencies, a summer adds two gain compensation signals, the ratio of the second to the first being a function of temperature. The summed signal may then be multiplied by a function of temperature. The summed signal may then be used to provide non-linear temperature compensation to the gain.
