Good one, Christophe ... I'm listening to it at the moment. The live stuff has a nice sense of space -- might send it through to the Foo Fighter's producer, could give him some ideas ... . Or maybe he would "protest" ...

Also, like the guitar sound on the studio take, something strange about the vocals though ...

Thanks for that,
Frank

Thanks a lot. Very nostalgic 'souvenirs'. ... We were so young.

Question for John

Designing With Field-Effect Transistors. Second Edition

I can get this book quite cheaply in the UK

Will it be of any interest / use to someone like me how does not have high level maths ?

thanks

I can't say, mike, without the authors name.

The effect is slew rate dependent. The current density modification is directly proportional to the currents induced within the conductive material. The currents are directly proportional to the induced voltage ala Faraday's law of induction.

The resistance increase is a function of the absolute value of the rate of change of the current within the wire which is creating the magnetic field. That is why Ed sees the second harmonic.

Had one of my favorite thought experiments this morning, consider a tri-wave constant alternating slew rate. Constriction is constant (?) therefore no modulation. I might be on the fence again.

IMO a good book. 1990, ISBN 0070575371. Wurcer pointed out that Ed Oxner's view of ion implantation as anathema for noise is a bit outdated, which has led me to be a bit more cautious about evaluating Ed's remarks here and there, but with that minor caveat I'd recommend the book. And in fact I don't even think the anti-implantation view is expressed within it

That's a minor point unless Ed also thinks nothing has changed in 33yr. It was a problem smart people worked on it a long time.

But is this book suitable / useful for someone without high level maths ?
