After a brief break, I found myself revisiting latching relays—not just as components, but as puzzles waiting to be solved.

Here’s a nostalgic vibe of an awesome analog chip from the 1990s era that’s still making an impact in audio designs.

A software suite powering oscillators and clocks claims higher time synchronization accuracy than quartz-based solutions.

There are many options when you need to splice wires. In addition to formal two-piece connectors, there’s the widely used ...

Why get up close and personal with a resistor when you can tweak it from a distance? Remote variable resistors make analog circuit control easier, neater, and a lot more fun. Well, we are about to ...

Engineers often use SPICE simulations for operational amplifiers to look at the stability of a proposed circuit. SPICE simulations are particularly frequent for high-speed amplifier applications where ...

One of the issues that beginning electronic engineers must grasp is the concept of impedance and impedance matching, epically with respect to transmission lines, cables, and connectors. This FAQ ...

A capacitor measured with a $100 handheld multi-meter can give a substantially different result than the same capacitor measured with a $10,000 LCR meter. That same capacitor measured with two ...

There is a lot of demand for the tiny speaker in smart glasses and smartwatches to be even smaller and lighter. However, the century-old micro-speakers built around a dynamic driver, coil, and ...

Table 2 Loop filter parameters are shown for a down-converted architecture. Source: Texas Instruments Figure 7 shows the measured result and simulation obtained from the LMX2820 chip, which has a ...

Tony Pialis, whose company Alphawave Semi has been acquired by Qualcomm for $4.2 billion, is a man associated with connectivity IP. But how did it all start for Pialis, who holds a bachelor’s and a ...

In operational amplifier stability, one rule of thumb is to allow 45 degrees of phase margin. Other design guidelines state that 60 degrees is best; still others say that 30 degrees is sufficient.
