Avalanche Pulse Generator Build Using 2N3904

Avalanche transistors can be used to generate fast rise time pulses. Their usage in the hobby world was made popular following an application note (AN72) by Jim Williams and was further publicized via this EEVBlog video. Many people have built such avalanche pulse generators for oscilloscope bandwidth measurements. In this post, I will show you the one I built using a general purpose BJT as well as some rise time measurements. Continue reading ‘Avalanche Pulse Generator Build Using 2N3904’ »
