Transistors are also integral to high-frequency applications like the oscillator circuits in radio signal generation. Transistors possess some unique characteristics that make them ideal for use in ...

[Qrp-Gaijin] shows how to do it with a single transistor ... Changing the oscillator topology did the trick. A tuned circuit prevents the oscillator from having sufficient gain at the fundamental ...

As with many inventions, two people had the idea for an integrated circuit at almost the same time. Transistors had become commonplace in everything from radios to phones to computers, and now ...

Much more so than the invention of the bipolar junction transistor in 1947 by Bardeen ... Logic representation of Fairchild’s ring oscillator circuit. Interestingly, there’s a clear asymmetry ...

For input signals with high noise, a two-transistor cascoded SO is preferable. The output buffer, Q 2, provides protection between the oscillator and the output world. However, if you want to simplify ...

One of the first big improvements of this build style is the shift from the originally used spark gap commutator to that of a direct AC drive via a MOSFET oscillator. This improves the primary ...

If made with a bipolar transistor, then “A” is an emitter ... The Clapp oscillator has several advantages over the Colpitts oscillator. The transfer function peak of the Clapp circuit is narrower than ...
