阅读：777发布：2022-10-23

专利汇可以提供Pulse driver circuit apparatus专利检索，专利查询，专利分析的服务。并且Pulse driver circuit apparatus of the type suited for use as a means to energize GaAs laser diodes and the like wherein a first transistor operated in the avalanche mode is used to rapidly inject a stored quantity of charge into the base of a power transistor which serves as a gate for discharging a second capacitor into the low-impedance laser diode or other output apparatus.，下面是Pulse driver circuit apparatus专利的具体信息内容。

权利要求

1. Pulse driver circuit means for providing high current pulses of short duration, comprising: a first transistor having a first base, a first emitter and a first collector, said first transistor being biased to operate in the avalanche mode; a second transistor having a second base direct connected to said first emitter, a second emitter, and a second collector, first power supply means coupled to said first collector; second power supply means coupled to said second collector; load means coupled to said second emitter; a first capacitive potential storage means coupled to said first collector for discharge through said first transistor into said second base; and a second capacitive potential storage means coupled to said second collector for discharge through said second transistor into said load means, whereby an input pulse applied to said first base causes said first capacitive potential storage means to discharge through said first transistor into said second base thereby causing said second capacitiVe potential storage means to discharge through said second transistor into said load means.

2. Pulse driver circuit means for providing high current pulses of short duration, comprising: a first transistor having a first electrode, a second electrode, and a third electrode, said first transistor being biased to operate in the avalanche mode; a second transistor having a fourth electrode direct connected to said second electrode, a fifth electrode and a sixth electrode; first power supply means coupled to said third electrode; second power supply means coupled to said sixth electrode; a first capacitor coupled to said third electrode; a second capacitor coupled to said sixth electrode; and an injection laser coupled to said fifth electrode, whereby an input pulse of a predetermined potential applied to said first electrode causes said first transistor to couple charge stored in said first capacitor into said fourth electrode thereby causing said second transistor to couple charge stored in said second capacitor into said injection laser.
