Buffer Circuit Diagram. And the output impedance is very low. Two inverter or not gates connected in series so as to invert then re invert a binary bit perform the function of a buffer.
Current buffer circuit diagram below is the circuit diagram of a simple mosfet current buffer. A non linear buffer amplifier is sometimes used in digital circuits where a high current is required perhaps for driving more gates than the normal fan out of the logic family used or for driving displays or long wires or other difficult loads. Applications of current buffers.
Current buffer circuit diagram below is the circuit diagram of a simple mosfet current buffer.
This means that the buffer can be modelled as a voltage controlled voltage source that has a gain of one. And the output impedance is very low. Buffer schematic diagram and circuit description click here for a higher resolution larger schematic. The input impedance of the op amp buffer is very high.
