Abstract
An integrated circuit device has a device main bodyhaving a predetermined circuit function of providing an output corresponding to an input thereto, and is provided with a power supply sectionfor receiving through a coilelectromagnetic wave energy applied from outside to generate predetermined internal electric power required to operate the integrated circuit device. The integrated circuit device further includes a calibration data acquisition circuit (operation control section) for detecting the output of the device main bodyoperated in a predetermined operating environment to obtain calibration data on the device main body, and a nonvolatile memoryfor storing the calibration data. Using the calibration data stored in the nonvolatile memory, the output of the device main bodyduring actual use of the integrated circuit device is corrected (calibrated), whereby deviation or dispersion of the output or output characteristic of the device main body attributable to an individual difference thereof is efficiently corrected with ease.
