A driving circuit includes first and second input signal terminals, first and second output signal terminals, constant current sources, first and second transistors having control terminals connected to the first and second input signal terminals, third and fourth transistors each having a control terminal to which a first bias voltage is applied, first and second inductors each having a first inductance, and third and fourth inductors each having a second inductance larger than the first inductance. The driving circuit further includes fifth and sixth transistors each having a control terminal to which a second bias voltage is applied, outflow terminals connected to inflow terminals of the third and fourth transistors via the first and second inductors, and inflow terminals connected to the first and second output signal terminals via the third and fourth inductors.
