    摘要: An electronic circuit comprising an amplifier includes an output terminal (OUT) for supplying an output signal (Vout) to a load, the amplifier comprising an output transistor (N2, P1) having a first main terminal coupled to a supply voltage terminal (VSS, VDD) of the amplifier, a second main terminal coupled to the output terminal (OUT), and a control terminal. In order to avoid that the output transistor (N2, P1) can enter its linear state which would cause the amplifier to act unacceptably slow for some purposes, the electronic circuit further comprises a controller adapted to prevent the output transistor (N2, P1) to enter its linear state whereby the controller is arranged for reducing a control voltage (Vcntrl) between the control terminal and the first main terminal when an output voltage (Vout) between the second main terminal and the first main terminal is below a defined level.
