Abstract
A fast scanning voltage ramp generator including at least one chain of N two-pole avalanche transistors in series and a set of N+1 zener diodes in series between a high voltage power supply and ground, where N is an integer number≧2. A streak camera can utilize this type of generator.
Claims12
Fast scanning voltage ramp generator comprising:
- at least one chain of N two-pole avalanche transistors in series and a set of N+1 power supply elements in series, where N is an integer number≧2, an emitter and base of each transistor being connected to each other and also being connected to a collector of a next transistor in the chain;
- an input circuit generating a voltage pulse connected to one of two transistors at ends of the chain,
- wherein the set of N+1 power supply elements in series is formed by a set of N+1 zener diodes in series between a high voltage power supply and ground, and
- wherein the collector and the emitter of each transistor in the chain are connected to a cathode and to an anode of a corresponding zener diode through at least one resistance, and are connected to the ground through a corresponding capacitor.
