Abstract
An output circuit of a charge mode sensor includes a second resistor and an operational amplifier. The second resistor connects an output portion of the charge mode sensor and a ground. The operational amplifier is configured to output a detection signal that varies in accordance with an amount of charge kept in the charge mode sensor. The operational amplifier includes an inverting input portion, a non-inverting input portion, and an output portion. The inverting input portion is connected to the output portion of the charge mode sensor via a sensor cable. The non-inverting input portion is connected to a reference voltage. The output portion is connected to the inverting input portion via a first resistor.
