Simple Voltage Amplifier Circuit. Diagram of this simple amplifier. An essential part of building a voltage amplifier is knowing how much your voltage will be.
Please use a good quality one battery for this amplifier. If we are beginner then this post for us. The op amp has low output impedance 10 100ω.
This circuit is used to buffer a high impedance source note.
This circuit is used to buffer a high impedance source note. However with a transistor and the correct biasing we can produce the same voltage amplification effect of an op amp circuit. Since the output adjusts to make the inputs the same voltage vout vin i e. No current flows into the input rin the output is fed back to the inverting input.
