Buffer Circuit Transistor. This buffer uses an npn transistor as the amplifier. 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.
Only one more common emitter transistor stage is added to re invert the output signal. In the circuit example a transistor buffer is used to decrease the loading effect on an oscillator the input circuit which is not shown by reducing the interaction between the load and the oscillator. Thus the power dissipation is about 600 ma 9 v 5 4 w.
A buffer might be used to impedance match an input circuit to an output circuit.
A buffer might be used to impedance match an input circuit to an output circuit. Now turn on your amp and play. A buffer might be used to impedance match an input circuit to an output circuit. Plug the 18vdc power supply in the power jack j1.
