Abstract:
Embodiments of the invention concern a circuit for pulling a potential at a node towards a feed potential which is present at a potential feed. The circuit has a first transistor with a controllable conductive path and in addition a resistive element. The controllable conductive path of the first transistor and the resistive element are coupled in series between the potential feed and the node. Furthermore, the circuit has a control element configured to control the first transistor so that a resistance of the controllable conductive path of the first transistor can be changed depending on a voltage drop at the resistive element. Furthermore, a method for pulling a potential at a node towards a feed potential and an integrated circuit with a pad which is pulled to the feed potential in the absence of an information carrying signal which is received or send by a functional circuitry of the integrated circuit.
