Provided is a differential amplifier wherein: a first compensation capacitor (Ca) is connected between the control terminal of a first differential input transistor (M1, M1b, M1c, T1) and a first current-carrying terminal thereof; and a second compensation capacitor (Cb) is connected between each of the first current-carrying terminal of the first differential input transistor and a first current-carrying terminal of a second differential input transistor (M2, M2b, M2c, T2) and either a first power supply line (7) or a ground line that is at the same AC potential as the first power supply line. The capacitances of the first and second compensation capacitors have been set such that the difference in amplitude between AC noises propagating between the control terminals and first current-carrying terminals of the first and second differential input transistors is within a predetermined value range. |
