    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.
