a very simple op amp circuit with some detail omitted If you open this circuit in the Falstad simulator, you’ll see two sliders to the right where you can tweak the input voltage. If you make ...

The graphs show a high nominal output current of 5 mA to better display the higher end of the current-amplitude range. Depending on your application, you can optimize each circuit's dynamic impedance ...

Op amps. Often the first thing that many learn about when beginning the journey into analog electronics, they’re used in countless ways in an overwhelmingly large array of circuits. When we ...

Dyer's article on simulation of the 12AX7 and the K2-W vacuum-tube op amp. 1. The model for the K2 ... the two neon lamps used in the actual circuit as voltage regulators. Positive feedback ...
