Paul,
The article in question is very long and very detailed. There are several parts where the turn on/turn off times are discussed. The bibliography is several pages long. It is beyond my capabilities to copy the article at this time.
I would suggest, if you insist on fooling with class E amps, that you invest in the paper that includes the entire article. (unless you can find someone that can copy it for you)

Would anyone have copies of QEX for January and February 2001? I do
know the 2001 periodicals CD-ROM is available. However I am not
certain if the information I seek is actually in the relevant QEX
articles and can't afford to buy it blindly. Please drop me a line
if you have these issues and could skim a couple of articles...
Specifically I am working on design of a Class E amplifier. I
downloaded the ClassE program from Tonne Software. It says the
design equations came from Jan/Feb '01 QEX articles. One of the
design variables in the program is Fall time. It's the only one I
don't understand. It seems to have only a subtle affect and I need
more information on it.
