With so much analog-circuit design being done by automated tools and circuit-performance analysis done with tools such as Spice, it may seem anachronistic to actually go through a basic circuit in ...

Most circuits that require current loss detection use expensive isolation amplifiers. This circuit solves that problem with a simple and low-cost method to detect current loss of 4-20 mA. To view the ...

Building simple circuits with copper tape, LED bulbs, resistors, and watch batteries is not as simple as you might think. Notre Dame Elementary School STEM students are putting the engineering design ...

The current-mode or peak-current-regulating switching converter is a familiar, almost dominant, power supply circuit consisting of few parts and is usually designed with “cookbook” procedures from PWM ...

This animation shows how pairs of dangling bonds can serve as atom-sized binary bits in digital circuits. Credit: Robert Wolkow/U. Alberta In the ongoing drive to make circuitry ever smaller and more ...

Electric circuits can feel intimidating, but with the right approach, they become logical puzzles you can solve step-by-step. From understanding voltage, current, and resistance to applying ...

Using simple components such as oil, salt water, lipids and proteins, plus routine genetic engineering techniques, it is possible to create simple nanofluidic ...

This file type includes high resolution graphics and schematics when applicable. In some situations, it becomes necessary to drive a MOSFET (or IGBT) with a voltage that’s lower than its ...
