Found in an American publication in 1967, this circuit generates pulses for the triggering of a LASER of the time. The circuit receives a signal in the form of a ramp producing a rectangular signal.
The operational amplifier taken as an example is uncommon today, but the configuration can be made...
The integrated circuit used in this regulator is not easy to obtain, since the publication is from...
This configuration was obtained in a 1977 FET Databook. The circuit can be practically any JFET...
