Many analog signal-chain circuits require ac-coupling to eliminate unwanted dc voltages or offsets. The simplest means to ac-couple is to use a capacitor in series with the signal path, thus forming a ...

Using a fixed-DC architecture removes the complex process of voltage variability in solar-plus-storage projects. Image: Lockheed Martin. For a long time AC-coupled solar-plus-storage was the preferred ...

Modern operational amplifiers (op amps) and instrumentation amplifiers (in amps) provide great benefits to the designer, when compared with discrete semiconductors. But all too often, some very basic ...
