发明名称 Electric charge type sensor
摘要 An electric charge type sensor includes a detection element detecting a physical property to be detected and outputting a detection signal in the form of electric charge and an operational amplifier having an output terminal, an inversion input terminal and a non-inversion input terminal. The inversion input terminal is connected to the detection element while the non-inversion input terminal is connected to a reference potential. The electric charge type sensor further comprises a feedback capacitor, a voltage divider and a feedback resistor. The feedback capacitor is connected between the output terminal and the inversion input terminal. The voltage divider is connected to the output terminal for providing a partial voltage of an output voltage at the output terminal. A feedback resistor is connected between the voltage divider and the inversion input terminal.
