Abstract
The present invention relates to a buffer for logic signals including a MOS output transistor of a first conductivity type connected by its source to a first supply potential, the drain of this transistor forming an output terminal of the buffer; a control transistor for controlling the output transistor connected between the gate of the output transistor and a second supply potential; a third transistor of the first conductivity type connected between the gate of the output transistor and the first supply potential and controlled to maintain the gate-source voltage of the buffer close to a threshold voltage so that the output transistor operates as a current generator; and a fourth transistor connected to render floating the gate of the third transistor when the potential on the output terminal is close to the first supply potential.
