    摘要： An integrated buffer circuit includes a first series circuit connected between a first supply potential and a second supply potential (ground). The first series circuit has a voltage-controlled first constant current source, a first field effect transistor having a gate forming an input of the buffer circuit, a circuit node between the first current source and the first field effect transistor forming an output of the buffer circuit, and a first control input for controlling the first current source with a reference potential having a constant potential difference relative to the first supply potential. A second series circuit is connected between the first supply potential and the second supply potential. The second series circuit has a first resistor, a second constant current source furnishing a current being independent of the first supply potential, and a circuit node between the first resistor and the second current source, establishing the reference potential and being connected to the first control input of the first current source.
