This circuit is from the National Semiconductor's Linear Applications Handbook of 1994. The circuit can be implemented with equivalent operational. The detected voltage is given by the diode.
We found this circuit in a 2002 documentation. It still uses old type plugs, but it can be adapted to...
This circuit was proposed by a 1965 Electronic Design. Its purpose is to widen the line transients...
The circuit shown can measure currents less than 1 uA and is powered by two 1.5 V batteries in a...
