This article discusses the low current input circuit ideas using the 6N139 series optocouplers. A few of the circuit designs are signal detection, transient detection, matrices and non-loading line ...

The op amp-based current sensing circuit described here is not new, it has been around for some time, but with very little discussion of the circuit itself. Somewhere along the line it was informally ...

H-bridge buck-boost ICs are widely used in applications requiring a constant voltage or current source even when the system ...

For the PDF version of this article, click here. When designing converters, it is often desirable to measure the dc current coming into the converter. This is particularly true when batteries are ...

The activity of neuronal circuits of the neocortex underlies our ability to perceive the world and interact with our environment. During development, these circuits emerge from dynamic interactions ...
