Using ultracold atoms and laser light, researchers recreated the behavior of a Josephson junction—an essential component of ...

H-bridge buck-boost ICs are widely used in applications requiring a constant voltage or current source even when the system ...

It isn’t unusual to expect a precisely regulated voltage in an electronic project, but what about times when you need a precise current? Over on EDN, prolific [Stephen Woodward] explains how to use a ...

The Seeker quantum processor from Quantum Circuits now supports Nvidia's CUDA-Q, enabling developers to combine quantum computing with AI and machine learning. Quantum Circuits announced that its dual ...

In physics, we have a bunch of constants that are used in models to explain how the world works. These are fixed numbers that we plug into equations along with our variables. For example, the ...

At first glance, [RobBest]’s constant current source looks old school. The box is somewhat old-fashioned, featuring switches and binding posts. Most importantly, there’s a large analog meter ...

The ever innovative and prolific Mr. Woodward has offered “PWM-programmed LM317 constant current source,” an intriguing programmable constant current source which elicited a lively conversation in its ...

The film explains how electric current is generated at power plants and delivered to homes through wires. It describes the concept of electric circuits, including closed and open circuits, and the ...

This design idea reprises another “1A, 20V, PWM controlled current source.” Like the earlier circuit, this design integrates an LM3x7 adjustable regulator with a PWM DAC to make a programmable 20 V, 1 ...

A team of researchers unlock heat flow principles in ultra-thin metals, paving the way for faster, smaller, more efficient computer chips. In a leap toward more powerful and efficient computer chips, ...

We have examined voltage sources, and now we can examine their less-known but necessary complement, the current source. Figure 1. The schematic symbol for a current source can be either a circle with ...
