As semiconductor technologies move into millimeter-wave and sub-terahertz frequencies for next-generation applications, engineers need to accurately characterize transistor performance across ...

Last time, I wrote about starting to build a TLM103-style transformerless condenser microphone on a universal circuit board. Looking only at the circuit diagram, it doesn't seem that complicated. The ...

Apple A20 Pro teardown by TechInsights confirms TSMC’s 2nm N2 nanosheet transistors are now in mass-market smartphones -- the first independent validation of foundry claims. The September 22 analysis ...

A transistor is a switch with no moving parts. A small voltage on the gate controls a much larger current between source and drain, and a chip built from billions of them can hold and process an ...

Commercial high-current benchtop power supplies can be expensive and bulky. In this project, we construct a high-performance 0–30V, 10A adjustable DC power supply using easily obtainable linear ...

There are countless reasons why working on a DIY project can prove beneficial — it's a great way to pass the time, build your confidence, stoke your creativity, and foster self-reliance by helping you ...

Modern computers are towers of glass and metal with very few large deviations from one to another. Monitor A will go against B, except you can’t tell them apart unless they’re on. At least, that is, ...

Optocouplers frequently fail without a sound in labs or during repairs. The package appears to be undamaged, but there may be no output from the LED source or the photosensitive output stage. Testing ...

Colleen Fazio began her amp repair journey 10 years ago in Illinois. She has since moved to Southern California, where she repairs and builds tube guitar amplifiers in the Fazio Electric workshop.

Analog computing has gained increasing attention for its potential in artificial intelligence hardware. The computation in traditional analog systems relies on use of intrinsic physical quantities ...

Article subjects are automatically applied from the ACS Subject Taxonomy and describe the scientific concepts and themes of the article. Utilizing carbon nanotubes (CNTs) or graphene for electrode ...

Abstract: The high-linearity and low noise amplifier has been developed as a core module to improve the testing accuracy and weak signal capture ability of the high-precision digital multimeter. This ...
