    • An electronic circuit includes transistors having first to third terminals and the third terminal is used for controlling current between the first and second terminals. The electronic circuit comprises a cascode amplifier (10) having an input transistor (QI) whose third terminal receives an input signal (IN) and an output transistor (QO) whose first terminal is connected to the second terminal of the input transistor (QI), whose third terminal is connected to the ground potential through a capacitor (C1), and whose second terminal outputs an output signal, and a control circuit (20) having a control transistor (QC) whose third terminal receives a control signal and a diode (D) connected in series to the first and second terminals of the control transistor (QC). 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) of the control circuit (20). The electronic circuit has a reduced signal switching time.
