Noise analysis is very important in many analog and RF receiver circuit design since the received signals are very weak. In case of differential amplifiers the noise appear as common mode signal and ...

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 design of bias networks for any RF power amplifier therefore plays an important part in establishing stable operation. The subject has a curious history, which takes us into the murky waters of ...

Amplifiers and oscillators are important circuits that appear in many different configurations and perform many different functions in modern electronics. Most amplifier and oscillator circuits were ...

After recently putting together the paper tape reader for his custom tube-based UE1 computer, [David Lovett] did get ...

After a brief review of the history of the K2-W vacuum-tube op amp, an LTspice model is used to create its schematic in ...
