Actually, to be nitpicking, some diodes have a negative resistance region
and can be used as active devices: tunnel diode oscillators (or amplifiers
but they are messy with two terminal devices) anyone?
And yes, I do use tunnel diodes, in bare dies actually. I bonded a couple of
them
last Friday, but am still fighting problems with the attachment of the backside,
which is the cathode for that particular model, on the substrate with
conductive
(silver) epoxy.
