A Blu-ray player must be able to detect the microscopically tiny pits on DVDs in order to play back a film. Therefore, the question arises: Can a Blu-ray player also "see" other structures?...

For decades, I’ve had a fascination with voltage-to-frequency converters and the 555 analog timer chip, and therefore a double obsession with VFCs based on the 555...

This power management tip introduces the two different circuits for a positive-to-negative voltage conversion and for a negative-to-positive voltage conversion...

After more than fifty years of continuous production in bipolar and fully half that in CMOS, there’s really neither room nor reason to question the value and versatility of the venerable 555 analog timer...

The pages of Design Ideas have recently been awash in a veritable cascade of designs for variable frequency oscillators with frequency ranges tunable over multiple decades...

A tiny DC to DC buck converter board is useful for many applications, especially if it could deliver currents up to 3 A...

Vishay Intertechnology introduced a new compact, ready-to-use linear position sensor designed for high accuracy performance in demanding environments...

The schematic is rather trivial. A voltage regulator brings down a supply voltage (which might be from a car battery) to 5 V. An additional built-up voltage regulator generates an adjustable voltage of 1.95 V...

A while back I was challenged by a visitor to the website. He needed a very loud sweeping siren type audio sound generator powered by 3 V...

STMicroelectronics announced the Stellar P3E, the first automotive microcontroller with built-in AI acceleration for automotive edge intelligence...
