Pulse signal generating circuit and generator

Abstract

The invention provides an amplitude increasing and width reducing circuit unit and a pulse signal generating circuit and generator comprising the amplitude increasing and width reducing circuit unit. According to the amplitude increasing and width reducing circuit unit, two avalanche transistors which are cascaded are used as a basic unit circuit to construct the nanosecond balance pulse signal generator, and compared with a pulse generating circuit composed of a single avalanche transistor, pulse signals generated by the nanosecond balance pulse signal generator are large in amplitude, the pulse front edges are steep, and circuit reliability is high.

Problems solved by technology

[0005] However, the existing amplification and width reduction circuit unit is composed of a single-stage avalanche triode, and the balanced pulse signal generated by it has a small amplitude, and the pulse bottom width is relatively wide, and the reliability is relatively low; at the same time, more amplification The widening circuit unit adopts a series cascading form, and only needs to provide a trigger signal to the single avalanche triode at the lowest level. However, this type of circuit has poor reliability, and the damage rate of circuit devices is high, so the achieved effect is not ideal.
