Abstract

PURPOSE:To secure a direct current balance with one capacitor by executing the direct current negative feedback of a feedback 1 to a first differential amplifier and inputting the difference between an output voltage and the voltage of the capacitor to constitute the negative feedback into a second differential amplifier. CONSTITUTION:An output terminal 4 of a differential amplifier 1, an inverting input terminal 1b and one side input terminal 2a of a differential amplifier 2 are respectively connected with resistance 12 and 8, the inverting input terminal 1b and other side input terminal 2b of the amplifier 2 are connected with a resistance 13, the input terminal 2b and a ground are connected with a capacitor 14 and the input terminal 2b and an output terminal 4 are respectively connected with a resistance 15. By the constitution, the direct current negative feedback is applied to the amplifier 1 with a feedback ratio '1' and the difference between the voltage of the capacitor 14 and the voltage of the output terminal 4 to constitute the negative feedback is added to the differential input terminal of the amplifier 2. As such a result, for the differential input of the amplifier 2, the direct current balance is held regardless of an input Vi, for the differential input of the amplifier 1, the gain of the amplifier 1 is largely set and thus, the direct current balance is held regardless of the input Vi.
