Designing and building discrete operational amplifiers is a fascinating business for me.

The OP-AMP
Page 1 Go to: P2 P3 Before we describe anything technical, let's see one in action. An op-amp can be connected to a single voltage rail (called UNIPOLAR SUPPLY - 0v to Vcc ) or a dual voltage rail (called BIPOLAR SUPPLY +/-Vcc ).
Operational amplifier applications
This article illustrates some typical applications of operational amplifiers .

Discrete Op Amp Designs
The basis of the entire Tonelux designs centers around our two new discrete op-amps, the TX-240 and the TX-260. Why did we call them that?
Two 6-volt batteries Four NPN transistors -- models 2N2222 or 2N3403 recommended (Radio Shack catalog # 276-1617 is a package of fifteen NPN transistors ideal for this and other experiments) Two PNP transistors -- models 2N2907 or 2N3906 recommended (Radio Shack catalog # 276-1604 is a package of fifteen PNP transistors ideal for this and other experiments) Two 10 kΩ potentiometers, single-turn, linear taper (Radio Shack catalog # 271-1715) One 270 kΩ resistor Three 100 kΩ resistors One 10 kΩ resistor Lessons In Electric Circuits , Volume 3, chapter 4: "Bipolar Junction Transistors"
