Initially imagined by Nikola Tesla in the early 1900s, the concept of a world wide web didn’t see creation until 60 years later. Take a trip alongside the history of the internet. Almost everyone around the world has access to and uses the ...

A new control loop architecture is designed to generate very low noise voltages. This can be utilized by both linear and switching regulators. In addition to the low noise achieved, the level of noise becomes independent of the set output voltage. ...

Basic programmable rheostats For many variable resistor (rheostat) applications, one of the device’s terminals is connected to a voltage source VS. Such a source might be a reference DC voltage, an op amp output carrying an AC plus DC signal, ...

You’ve got an apparently simple design requirement on your latest AC-line powered project: provide a distinctly illuminated indicator to show that the unit is plugged into the line and that power is “on,” meaning that the line is ...

What’s going on at Intel, the largest beneficiary of the U.S. push to onshore chip manufacturing? While the semiconductor industry was still reeling from a Bloomberg report about TSMC in talks for a controlling stake in Intel Foundry at the ...

Capturing transient analog signals with a microcontroller normally involves adding a full-fat peak-hold circuit as an external peripheral. This novel approach minimizes that extra hardware by using a µP’s ability to switch its pins ...

A previous article suggests that most digital output waveforms follow a nearly Gaussian profile ( Reference 1 ). Let’s test that theory. Figure 1 depicts the rising edge from a Texas Instruments DL100-44T LVDS ...

Which step in Figure 1 best approximates the digital signals you work with every day? The piecewise-linear step starts with a jerk, mindlessly follows a perfectly uniform ramp, and smacks hard into its upper limit. Real signals don’t do that. ...

Introduction High precision op amps enable system designers to create circuits that condition signals (amplify, filter, and buffer) while maintaining the precision of the original signal. When information is contained in very small variations of ...

Whether its buck, boost, or buck/boost, internal or external switch, milliamps or tens of amps, a literal cornucopia of programmable output switching regulator/converter chips are commercially available. While the required external Ls and Cs (of ...
