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 ...

You have voted. Unity-gain-stable op amps won in a landslide—they’re far more popular than decompensated op amps. What’s this all about? Unity-gain-stable op amps (let’s call them UGS) are stable in ...

In a balanced op-amp circuit, the op-amp inputs see equal impedances looking into the circuit. Balanced circuits provide better performance by cancelling some input errors and have a simple R F /R I ...
