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 ...

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.

Editor's note: This article will be in two parts. This Part 1 will discuss latest advances in 'Zero-Drift' Op Amps and Noise. Self-correcting or ‘Zero-Drift’ operational amplifiers, as this device ...

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 ...

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 ...
