  • Patent number: 5764541
    Abstract: A method and apparatus for measurement signal compensation comprises providing an analog-to-digital converter that includes a dual slope integrator. A microprocessor controls the reference voltage applied to the integrator. An amplifier having a switchable gain, controls the amplification of the input signal to the integrator during the various phases of integration. An off-set compensation value is stored in a memory device for providing off-set compensation by charging a capacitor connected to the integrator. A full-scale rough adjust value is also stored on the memory device and is used as a specific reference to produce a reference voltage that is, in turn, used in the integrator during the negative slope phase. During the positive slope phase, the integration time is controlled by means of full-scale fine adjust values. The temperature dependent full-scale fine adjust values are produced from the preprogrammed values in memory by using interpolation techniques.
