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 to interpret and extract clipping issues in signal-path components. Nuances in assessing output dc error bands. A quick and easy way to simulate phase margin ...

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 ...
