PROBLEM TO BE SOLVED: To provide an operational amplifier that reduces a distortion of an output signal caused by nonlinearity of an open loop gain. ! SOLUTION: An operational amplifier 104 that comprises input terminals In10, In20 and output terminals Out10, Out20 of a plurality of gain stages 10, 20 and feeds an output signal Vo of the last gain stage 20 back to the input terminal In10, In20 includes a negative capacitance generation circuit 40 connected to either the input terminal In10, In20 or the output terminal Out10, Out20 of the plurality of gain stages 10, 20. !
