Unijunction transistors (UJTs) were common circuit elements several decades ago. A simple ramp generator could be built from a single UJT and a few other components (Fig. 1). 1. In a simple UJT-based ...

[Eric Wasatonic] had a box of SWB2433 transistors that he had very little information about. In order to discover their properties, he fired up his curve tracer to compare these transistors with more ...

If you’ve spent any time on hackaday.io, you may have noticed that more than a few denizens of the site are fans of “alternative” electronic logic. Aiming to create digital circuits from such things ...

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 ...

Researchers from the University of California – Riverside and Rice University have made the first single-transistor amplifier from graphene. The device is better than conventional amplifiers thanks to ...

Do you remember the Etch A Sketch drawing toy that lets you draw stuff with huge white buttons? I do. I loved that I could sketch something and then start over again. In fact, that doodling pad ...

What is a Single-Electron Transistor? A single-electron transistor (SET) is a nanoscale electronic device that allows the precise control of individual electrons. Unlike conventional transistors that ...

Graphene has already brought us the world's smallest transistor – twice – and now the one atom thick form of carbon that recently won its discoverers the Nobel Prize has been used to create a ...

Unijunction transistors (UJTs) were common circuit elements several decades ago. A simple ramp generator could be built from a single UJT and a few other components... Register or sign in below to ...

What happens to voltage gain when a bipolar transistor is operated at low voltages (Vce < 1V). In a previous circuit that operated at a quiescent Vce of 0.75V, voltage gain was demonstrably low. This ...
