If you want negative resistance, without using Tunnel Diode, you can use a NE-2/1A1 Neon Bulb if you can deal with the voltage, or a Lambda Diode. The Lambda Diode is made from two back-to-back JFETs. The selection of the JFET part number controls voltage set point. I'll be adding info on TD's and LD next month to my web site, in the mean time I can send you a couple of .GIF/JPEGs of the circuit if you want them. This was discussed on the list here long ago, but I don't see it in my current on line archives, which probably places it before 2001. Look under the 'Scalar' link at http://www.bpaddock.com/ , some of the discussion is listed there. -- � � � � � � � � � � http://www.softwaresafety.net/ � � � �http://www.unusualresearch.com/ http://www.bpaddock.com/ -- Author: Bob Paddock INET: [EMAIL PROTECTED] Fat City Hosting, San Diego, California -- http://www.fatcity.com --------------------------------------------------------------------- To REMOVE yourself from this mailing list, send an E-Mail message to: [EMAIL PROTECTED] (note EXACT spelling of 'ListGuru') and in the message BODY, include a line containing: UNSUB CHIPDIR-L (or the name of mailing list you want to be removed from).
