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 ...

We are all used to the op-amp, as a little black box from which we can derive an astonishingly useful range of circuit functions. But of course within it lurks a transistor circuit on a chip, and ...

Of digital electronics, a wise man once said that “Every idiot can count to one.” Truer words have rarely been spoken, because at the end of the day, every digital circuit is really just an analog ...

My hands-on introduction to operational amplifiers was in 1969 while in the army as a junior scientist in the Atmospheric Science Laboratory at the White Sands Proving Grounds. We had taken a ...

Sponsored by: Texas Instruments. Op amps solve most problems in analog circuit design—if you know how to use them. Here are some resources to help expand your op-amp knowledge base. Whenever you need ...

Modern op amps have much higher operating bandwidths than their predecessors. These new devices are excellent building blocks that can greatly simplify the design and construction of high-bandwidth ...

In an earlier blog (Comparing Op-Amp & Video Amp Topologies, Part 1), we examined the bandwidth and phase requirements for processing video. In the most recent blog, we looked at the AC and DC ...
