  • Integrated buffer circuit which functions independently of fluctuations on the supply voltage
    Patent number: 5774014
    Abstract: 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.
