This project demonstrates a single-stage common-emitter amplifier using an NPN BJT (2N2222 / TMBT3904). The amplifier converts a small AC input signal into a larger output voltage, showcasing one of ...

Solid-state device technologies, which are available to the amplifier designer, fall, broadly, into three categories: bipolar junction transistors (BJTs) and junction diodes; junction field effect ...

There is so much to learn about the single-transistor amplifier, that this brief tutorial hardly scratches the surface. This discussion considers only the common-emitter configuration as applied to ...

In this tutorial, we will show how, under certain conditions, a PNP transistor is equivalent to a single PN junction with a voltage-current characteristic appropriately shifted on the positive ...

This amplifier is a further development of "Versatile Audio Amplifier with the Current Output Signal". In this version I gave the input transistor T1 more linearity by using a MOSFET transistor BSS110 ...

We’ve previously remarked upon a generation lucky enough to be well-versed in microcontrollers and computersised electronics through being brought up on the Arduino or the Raspberry Pi but unlucky ...

Abstract: A method of analyzing common-emitter transistor video amplifiers has been given that is sufficiently simple and accurate for design work. This paper discusses the use of the above design ...

Abstract: We present a compendium of generalized expressions for the low-frequency voltage gain and terminal impedances of each of the three fundamental bipolar-amplifier topologies (i.e., common ...

[Paulo] just tipped us about an Excel based high frequency transistor amplifier calculator he made. We’re guessing that some of our readers already are familiar with these class A amplifiers, commonly ...

This monograph is concerned with the application of transistors to the audio-frequency amplifiers employed in sound broadcasting for which a high standard of performance is required. The prinicples ...
