Osc with .5.5mv supply voltage

A bimetallic thermo switch or buzzer type of thing?

Any resistor heated by any voltage generates heat. Heat is EM radiation. So that is an IR oscillator. Cigar?

link?

Are you referring to the supply voltage or the output?

If it's output, I guess R divider will do :)

Jamie..

You accept Cuban?

Same thing they did about the megatonnes of lead in car batteries I expect.

I hope they swallowed some ;-)

Hell, it is almost impossible to beat 350mV..

Not exactly what I was talking about. But go ahead and have a cigar, you deserve it for some of your other stuff! MikeK

Sorry, That's input voltage. Scopes looks like it reads 200mv output. MikeK MikeK

A Josephson oscillator generates approximately half-GHz per microvolt, and they are useable at 4.2K perhaps down to that one-uV bias. A HiTc JJ would generate about 2.65 teraHz at 5.5mV bias voltage - a colleaque actually uses one to illuminate a THz detector.

This is cheating (a sort of) really - the original FET circuit you referred to is clever and inspiring.
