But what to use for the starting point? Enter an old Radio Shack P-Box stereo amplifier kit. After a few modernizations and tweaks, the result is an 8-transistor stereo amplifier that’s ...

each using a single transistor. These circuits will allow you to observe the operation of a transistor as an amplifier, just as Walter Brattain did at Bell Labs in the winter of 1947. In the first ...

(Transistors at this level would be solely used as switches for binary coding, not as amplifiers.) In fact, such a tiny device might make use of the quantum weirdness of the ultra-small.

The chopper amplifier relied on the simple premise that, using 1950s technology ... and the germanium transistor AC amplifier was able to do a good job of working with the resulting 50 Hz square ...

In this chapter we will study the transistor differential-amplifier circuit ... As we will see in future chapters, differential amplifiers make it easy to build circuits that use negative feedback.

from mobile phones and computers to radios and amplifiers. Transistors are made using a complex process called photolithography. This involves creating a pattern on a silicon wafer using a process ...

The 33 preamp and 303 stereo power amp were Quad’s first transistor designs and were highly unusual inside and out. They were also well built and many remain in use and Quad offers a ...
