Voltage Gain Amplifier Circuit. R a inverting input resistor. In this project we will build a voltage gain op amp circuit.

Voltage amplifiers many times are built with op amp circuits.
In this project we will build a voltage gain op amp circuit. R f feedback resistor. Ap 10 log ap note that the dc power gain of an amplifier is equal to ten times the common log of the output to input ratio where as voltage and current gains are 20 times the common log of the ratio. However with a transistor and the correct biasing we can produce the same voltage amplification effect of an op amp circuit.
