Differential pairs in high-speed serial links require tight control of impedance, skew, and coupling to limit reflections, mode conversion, and crosstalk. At multi-gigabit data rates, small deviations ...

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.

Since the emergence of the wideband, fully differential amplifier (FDA) topology with the introduction of the AD8138 in 1999, a popular application of this type of device has been to convert a ...
