This circuit is from the LM107 manual. This operational is from the 80s, but the configuration is valid for any operational. The formulas give the gain of the circuit.
In the figure we have a simple amplifier stage for BC547 series transistors. The gain is...
We have here a very interesting project found in a 1982 publication. By the operation of the...
The circuit shown in the figure is suggested by National Semiconductor and makes use of an...
