Input circuit for receiving an input signal as well as a method for the adaptation of a working point of an input circuit

摘要

The present invention relates to an input circuit for receiving an input signal of an integrated circuit with a differential amplifier, whose first input of a predetermined reference voltage and at whose second input of the input signal can be applied, and to a current source for the operation of the differential amplifier at its operating point, characterized in that an adjustment circuit with a current source is connected to the operating point of the differential amplifier as a function of the predetermined reference voltage can be optimally adjusted.
