This JFET amplifier stage was found in the Encyclopedia of Electronic Circuits Volume 5 from 1995. Any JFET can be used and the bias controlled externally.
We found this circuit in a 2005 documentation. The circuit uses an infrared piezo sensor...
This circuit converts logic signals into a sinusoidal output. The components must be adapted to...
This circuit fires by burning the fuse when the input voltage exceeds the value referenced by the zener....
