I'm trying to create a controlled resistance "spike" and have had
little success so far. Basically, I want to create a resistance pulse
with a width of around 10nS that is variable from approximately 1
milliohm to around 10 milliohm. In other words, the resistance of the
device would be a nominal 1 milliohm, but would rise to around 10
milliohms for 10nS, then return to nominal. The resistance needs to be
electrically isolated from whatever is driving it. Obviously, rise and
fall times would have to be fast.
I experimented with a pulse generator and FET, but I really need
something like a fast LDR (light dependent resistor) because of the
isolation requirement. Any ideas?
Thanks,
Sam
