What does a "kick" look like on an oscilloscope?

This is starting to look like it is leading us back to the simple piece of wire.

The SM mention of a piece of wire probably was a reference to a completely bare piece of a length just long enough to hold that big spike.

You are doing the grunt and brain work. I'm just spouting crazy theories 8-)

Well, this is really getting interesting and fruitful. Having some fun with this.

A "piece of wire" indeed.

I have evolved the circuit and am now able to adjust the parameters of the circuit to produce a steady pulse train. Only the first pulse is at the supply voltage and of long pulse width. The subsequent pulses can be varied both in pulse width and in amplitude, but the two are inextricably-linked. The shorter the pulse width the higher the voltage.

For example, with a 20V supply, one setting produces 5ns wide pulses at about 150V. This at a PRR of 1.67MHz!

I pushed the supply up to 400V and achieved 15ns wide pulses at about 1600V. Again at a PRR of 1.67MHz. I doubt 400V would be the limit for this circuit, but certainly other methods for switching would need to be investigated. The old IRF840 can only handle about 500V.

Quite incredible how simple this circuit is yet the components are critical, and some tweaking is more than likely required. All this with two slow-switching MOSFETs.

After further research, I am convinced this circuit is patent material. I would like to disclose this circuit here but there are those (already identified) that may use it for monetary benefit. This has been discussed in another thread and now you can begin to see the effects.

I'll post some sim scope shots a little later.

PS. A piece of wire Not quite

[giantkiller]

Yes, 1 piece of wire. 'Microwatt draw', Moray.

@gk
yes that wire pices is good reciver

im vondering  how much  frek. is  catch in that wire HMM

[poynt99]

Once the pulse train stabilizes:

Vsupply = 20V
Pulse Amplitude ~ 130V
Pulse Width ~ 7ns
Pulse Repetition Rate = 5MHz
