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

Deep-brain recordings showed that Mounjaro and Zepbound briefly shut down the craving circuits linked to food noise in a ...

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 ...

Astronomers are rethinking one of cosmology’s biggest mysteries: dark energy. New findings show that evolving dark energy models, tied to ultra-light axion particles, may better fit the universe’s ...

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 ...

Over on his YouTube channel [Aaron Danner] explains biasing transistors with current sources in the 29th video of his Transistors Series. In this video, he shows how to replace a bias resistor (and ...

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 ...

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 ...

Voltage and the lesser-known current sources provide critical IC, circuit, and system functions. Voltage sources and their complement to current sources are essential elements of many systems, ...
