An electronic circuit includes: a first transistor having a control terminal, a first terminal, and a second terminal; a second transistor having a control terminal connected to the second terminal of the first transistor, a first terminal, and a second terminal connected to a DC power supply; a plurality of DC paths that are mutually independent of each other and supply DC currents from the first terminal of the second transistor to the second terminal of the first transistor; and distributed constant lines connected in series with the plurality of DC paths.
