ABSTRACT:
Input circuit and method for setting a termination voltage. One embodiment provides a method for setting a termination voltage of an input circuit of an integrated circuit, the input circuit having an input terminal for receiving a signal, the termination voltage being applied to the input terminal, the received signal being driven with respect to the termination voltage and being evaluated by a comparison with a reference potential, the termination voltage being generated and being set in accordance with a control signal, the control signal being generated in a manner dependent on a comparison of one or more signal levels of the received signal with an assessment potential, the termination voltage being set by means of the control signal in such a way that the reliability of the signal reception is maximized.
