Imagine that you have a voltage source in series with some source resistance feeding power to a variable load. The relationship between load voltage, load current, and cell current can be drawn as follows in Figure 1. Figure 1. The load voltage ...

Differential signaling is a common technique for obtaining high noise immunity for critical signals in high-speed digital pc-board systems. The pc board's traces, carrying differential signals, are often edge-coupled offset striplines, with the ...

Typical circuit An ongoing project (or gadget) called for a means of generating an audio output to represent a varying voltage level. Ho hum: that sounds like a voltage-controlled oscillator. But this signal was bipolar, spanning peaks ranging from ...

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 ...

From the micromixer topology by Barrie Gilbert [ 1 ], this amplifier allows a single-ended input to be converted to a Class A/B current output from a single supply. As shown in Figure 1 with an LTspice implementation, the circuit employs 6 bipolar ...

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 ...
