Microscopic fibers secretly shape how every organ in the body works, yet they’ve been notoriously hard to study—until now. A ...

A 240v outlet sits behind many big household upgrades, from a faster clothes dryer to a Level 2 EV charger in the garage.

When you get an MRI scan, the machine exploits a phenomenon called nuclear magnetic resonance (NMR). Certain kinds of atomic ...

Andy recommends favorite resources for basic op amp circuits and includes a portion of TI's AN-20. Test your knowledge with our op amp quiz; answer explanations are included. By 1969, a fledgling ...

Operational amplifiers (op amps) are almost the perfect amplifier. As long as you keep a few important details in mind, their imperfections will seem invisible. Figure 1. This simple non-inverting op ...

Amplitude modulation (AM) was first introduced to enable long-range wireless audio communication, representing a major advancement over wireless telegraphy using spark-gap transmitters. Understanding ...

Abstract: The transimpedance or current feedback operational amplifier (CFB op-amp) is reviewed and compared to a conventional voltage mode op-amp using an analysis emphasizing the basic feedback ...

What if you’ve already seen fragments of the future - without realizing it? In this thought experiment grounded in Einstein’s relativity, we unpack how a simple diagram changes our entire ...

A study on the use of electronic components that are fixed to a sheet of paper can be the answer to the massive problem of waste from electronics, like computers and cell phones. The circuit board, ...

Synthetic biology experiments suggest a “MultiFate” model for how genetically identical cells become the many different types found in complex organisms like us. The human body contains more than 200 ...

In the last Circuit VR we looked at some basic op amp circuits in a simulator, including the non-inverting amplifier. Sometimes you want an amplifier that inverts the signal. That is a 5V input ...
