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 ...

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 ...

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