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 ...

Current regulators (non-switchable and switchable) are a new family of useful and versatile devices targeted for use in communications, networking and power conversion circuits. Current regulators (or ...

Incremental-rotation or linear encoders are very common, but normally they do not provide a direction signal. This design shows an easy way to detect forward or reverse direction. Incremental encoders ...
