Today’s integrated video filter/driver devices can be designed into video systems (set-top boxes, PVRs, TVs) using a wide range of coupling and clamping configurations, such as input ac- or ...

Why should we do AC-coupling on SDI and, how does AC-coupling degrade our SDI signal? In past experiences, many engineers asked me this simple question, and because we are familiar with AC-coupled ...

In Comparing Op-Amp & Video Amp Topologies, Part 1, we mentioned that in a video amplifier, such as seen in Figure 1, a DC servo circuit is generally required to ensure that the average voltage in a ...

An engineer asked me for help when he encountered what appeared to be strange phenomenon while testing a prototype circuit in the system. He saw “mysterious” clipping distortion of the signal at the ...
