High-speed, high-voltage pulse generation using avalanche transistor pdf download

A fast (≤1 ns rise time) high-voltage pulser circuit was developed using 2N/2N transistors in avalanche mode as switching elements. This circuit has transistors in series stack configuration and provides ˜2 kV amplitude and ≤1 ns rise time.  · In this paper, the push pull configuration circuit is applied to the design of a high voltage pulse generator which is suitable for capacitive load. The high voltage pulse generator was designed and tested. All of the requirements, pulse repetition rate over 1 MHz, voltage adjustable from 0 V to V, rise/fall time less than 50 ns, and driven.  · A high-voltage pulse generator based on a self-matched transmission line with variable pulse amplitude and duration is developed. Two avalanche transistor stacks are used as switches. The pulse width is varied by adjusting the delay in triggering two switches whereas amplitude is adjusted by adjusting load resistance.

The design and performance characteristics of a high-voltage pulse generator for use with spark chambers in space are described. In order to minimize power consumption, the pulse generator is designed around a cold-cathode thyratron. The complete pulse generator consists of a thyratron pulser and an avalanche-transistor switching circuit. Download PDF. Download Full PDF Package. This paper. A short summary of this paper. Fig. 6 shows the high voltage quench pulse that is applied to the anode of the SPAD during the reset delay time. Some of the advantages of this method of generating quench and reset delay pulse are explained.1) Small delay in quenching the avalanche (10 ns.

It is also possible to use avalanche transistors connected in series and operated close to their avalanche breakdown as shown in Fig. 9 for switching very high voltage pulses [5]. For example, a.

Based on the above analysis, a high-speed and high-voltage pulse (HHP) generating circuit using avalanche transistors was designed, and its working principle and process were studied. To improve the speed of the output pulse, an approach of reducing the rise time of the leading edge is proposed.
