Abstract
An electronic circuit comprising an amplifier includes an output terminal (OUT) for supplying an output signal (V ) to a load, the amplifier comprising an output transistor (N , P ) having a first main terminal coupled to a supply voltage terminal (V , V ) 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 (N , P ) 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 (N , P ) to enter its linear state whereby the controller is arranged for reducing a control voltage (V ) between the control terminal and the first main terminal when an output voltage (V ) between the second main terminal and the first main terminal is below a defined level.
