ABSTRACT:
Non-inverting input terminals of first and second operational amplifiers having the same characteristics are connected together. A first circuit is connected between the inverting input terminal of the first operational amplifier and a first signal input terminal. A second circuit is connected between the non-inverting input terminal of the first operational amplifier and the first signal input terminal. The first circuit receives a feedback signal from an output terminal of the first operational amplifier. The second circuit is connected to a reference voltage source. A third circuit is connected between the inverting input terminal of the second operational amplifier and a second signal input terminal. A fourth circuit is connected between the non-inverting input terminal of the second operational amplifier and the second signal input terminal. The third circuit receives a feedback signal from an output terminal of the second operational amplifier. The fourth circuit is connected to the reference voltage source. The first, second, third and fourth circuits have the same element schematics.
