    摘要： A semiconductor device includes a reference voltage generating section configured to generate a first reference voltage and a second reference voltage based on a voltage supplied from an external power supply; and an AD (analog/digital) conversion circuit operating based on the first reference voltage to generate an AD conversion signal corresponding to an output signal supplied from an external device through AD conversion. The second reference voltage is supplied to the external device, and a ratio of the first reference voltage and the second reference voltage is kept to a constant value regardless of a temperature of the semiconductor device.

    摘要： A semiconductor apparatus includes an amplifying unit, a bias controlling unit, an AD converting unit and a controlling unit. The amplifying unit is configured to amplify an input signal to output an amplified signal. The bias controlling unit is configured to generate a bias voltage to be applied to the input signal. The AD converting unit is configured to AD-convert the amplified signal into an output signal. The controlling unit is configured to output a control signal to the bias controlling unit. The controlling unit outputs the control signal when an output value indicated by the output signal is equal to a predetermined value. The bias controlling unit changes the bias voltage in response to the control signal.

    摘要： A variation detection device has a processor, an AD converter converting a signal voltage output from a sensor to generate an AD converted value and outputting the AD converted value to the processor, a temperature sensor detecting a temperature of the sensor, and a memory storing a table which indicates a relationship between temperatures and initial values. When receiving the AD converted value, the processor identifies a temperature of the sensor based on an output of the temperature sensor, reads out an initial value corresponding to the identified temperature from the table, and calculates a variation between the initial value and the AD converted value.
