[Ynze] found a basic design that works, and built from there. One of the interesting things about [Ynze’s] amp, as well as many of the Gainclones, is the fact that they use no circuit board.

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 ...

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 prerequisites are a DC-AC course; a basic knowledge of algebra ... small-signal single and multi-stage amplifiers (using BJTs, FETs, and MOSFETs), and the frequency response of transistors for ...
