The very basics of operational amplifiers. Learn comparator, inverting, and non-inverting op-amp configurations. An operational amplifier, or op amp, is a dc-coupled high-gain electronic voltage ...

In my previous blog in this series, we looked at the video amplifier used in a piece of professional video equipment, the Sony BE-3000 video switcher/effects board. Figure 1 shows a video amplifier ...

Part 4 of this series recognizes that, in spite of all efforts to keep the EMI and RFI from corrupting the sensor signals on their way from signal source to the signal conditioning instrumentation.

As analog engineers, it’s tempting to fantasize about one day coming close to designing the ideal operational amplifier we encountered in college: infinite bandwidth, zero output resistance, and so on ...
