Characterizing SSBW for VFAs and FDAs. What's hiding in some fully differential amplifiers? Measuring response shape and harmonic distortion. Adding an input common-mode control loop to a legacy FDA.

How analog signal engineering is performed, in broad strokes. What are the component-selection considerations for new designs? What are VFAs and how are they used? Analog signal engineers specialize ...

Imagine some system as in Figure 1 with a forward signal path from “A” to “B” where signal delays through that path are too slow. Figure 1 A slow signal path If we do it right, the speedy feed forward ...

In Part 2 we related the impact on signal quality to some possible real-world basic signal and shield grounding choices (both the good and the bad). But, even in that brief discussion, it is clear ...

The research group in this study developed the world’s thinnest and lightest signal amplifier for bioinstrumentation and demonstrated high-precision monitoring of electrocardiac signals with reduced ...

Embedded systems are using sensors with increasing frequency. While industrial products have always used them for manufacturing control systems, consumer devices are starting to employ them more often ...

If you want to extract a signal from a huge amount of noise, a lock-in amplifier is the ideal tool. But when it comes to buying one, doing your homework first can avoid a costly mistake, advises ...

Audio amplifier fault diagnosis gets a fast reality check as Roberto Armani shows how a square wave exposes what a sine wave ...
