An electronic circuit includes: a first amplifying circuit to which a first input signal is inputted; a second amplifying circuit to which a second input signal is inputted; a first drain ground amplifying transistor provided between a first power source node and an output node with control over the gate by the output from the first amplifying circuit; a second drain ground amplifying transistor provided between the first power source node and the output node with control over the gate by the output from the second amplifying circuit; a common load element provided between the output node and a second power source node; a first negative feedback path for negative feedback from the output node to the input of the first amplifying circuit; and a second negative feedback path for negative feedback from the output node to the input of the second amplifying circuit.
