[time-nuts] AMC-123 patent (was: Re: Phase Noise of 74AC gates)

[Jeffrey Pawlan]

That is the first Norton patent. The later one was co-authored by Allen 
Podell and uses a single transformer with three windings.

I wrote a series of two articles on the SPICE and also Serenade simulation 
of a real constructed amplifier using the circuit in the second patent. 
The match, IP3, and NF are very good, both the reverse isolation is poor.
