An electronic circuit includes transistors having first to third terminals, the third terminal controlling the current between the first terminal and the third terminal. The electronic circuit includes: a cascode amplifier ( 10 ) including an input transistor (Q 1 ) receiving an input signal (IN) through the third terminal, and an output transistor (QO) having the first terminal connected to the second terminal of the input transistor (QI), the third terminal connected to the ground potential via a capacitor (C 1 ) and the second terminal outputting therethrough an output signal; and a control circuit ( 20 ) including a control transistor receiving a control signal through the third terminal, and a diode connected to the first and second terminals of the control transistor (QC) in series. The third terminal of the output transistor (QO) of the cascode amplifier ( 10 ) is connected to the ground potential through the control transistor (QC) and the diode (D). The electronic circuit has a reduced signal switching time.
