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.
With this circuit it is possible to keep the current in an LED constant even if the supply voltage...
This circuit was suggested by Motorola in its manual of components for optoelectronics (1987)...
This sensitive circuit can be designed with FETs such as BF245 and MPF102. The sensor is a silicon...
