Abstract
A processing circuit is provided which includes at least an integrator circuit which uses a reference voltage set to have a predetermined magnitude as an operation reference and which integrates a detection signal so as to convert the detection signal into a voltage waveform and a base voltage adjustment circuit which is connected between an input terminal and an output terminal of the integrator circuit and which adjusts the magnitude of a base voltage that is a potential when the detection signal in an output signal output from the integrator circuit is not present. As another form, a processing circuit can be adopted which includes at least one or more amplifier circuits which amplify an output signal from an integrator circuit and a base voltage adjustment circuit which is connected between a supply portion of a reference voltage fed to the amplifier circuit and an input terminal of at least one of the amplifier circuits and which adjusts the magnitude of a base voltage that is a potential when a detection signal in an output signal output from the amplifier circuit is not present.
