Another nice way to get an RNG is Avalanche breakdown. You can do this with reverse emitter-base breakdown in a BJT, or with a diode. This may take more voltage than you want to use in your process, but you can engineer the base-emitter junction if you've got a friend in process engineering. One other potential problem is long-term reliability, but that's a subject for another email. -- Riad Wahby [EMAIL PROTECTED] MIT VI-2/A 2002
