摘要
An operational amplifier circuit is constituted by first and second inverted amplifier circuits (A1, A2) that receive first and second input signals, a third inverted amplifier circuit (A3) that receives an estimated common-mode output signal and an output signal from the first inverted amplifier circuit and outputs first and second output signals, a fourth inverted amplifier circuit (A4) that receives the estimated common-mode output signal and an output signal from the second inverted amplifier circuit and outputs third and fourth output signals, where the estimated common-mode output signal is generated by adding the second output signal and the fourth output signal, and first and second non-inverted amplifier circuits (A5, A6) that receive the estimated common-mode output signal and feed it back to the first and second inverted amplifier circuits.
