We’ve seen lots of interesting conversations and Design Idea collaboration devising circuits for power switching using inexpensive momentary-contact SPST pushbuttons...

Nexperia introduced the industry’s first ESD diodes designed to protect 48 V automotive data communications networks against the destructive effects of electrostatic discharge events...

In many applications, it is not possible to measure distance to the target by establishing a physical contact. Typical examples include measuring presence of objects on a conveyor belt in logistic centers, or ensuring safety distances around moving robot arms...

Implementing a simple digital-to-analog converter by cascading a single pulse width modulator and an analog low-pass filter is nothing new. Nor is applying to a filter the sum of the outputs...

Lightning is one of nature’s most intense and unpredictable forces, but thankfully, we have got technology to help us stay ahead of the storm...

Lively discussions have sprung up here in editor Aalyia Shaukat’s Design Ideas regarding the limitations and quirks of, and design tricks for, the current control  topologies...

“Two halves make a whole” is a very old and often true maxim. For example, it’s almost always true when said about AC phase angle power control...

The ability to zero-cross when turning on AC line voltage to some loads may be advantageous...

A simple circuit can improve the dynamic performance of a phototransistor for use in low- to medium-speed applications as fast as 100 kbps, such as optical isolation of an RS-232C serial line...

Meters that indicate analog levels via a moving-pointer meter, a numeric display, or a column of LEDs typically occupy considerable panel area and require more than a casual glance to read...
