Erroll Dietz is a remarkable fellow. He started out at National Semiconductor as Bob Pease's
technician, and rose to become Chief Technology Officer.
Sometimes it's useful to add supporting documents, schematics, scope photos, simulations or other things to Usenet posts. By popular request I've added links to some of these, in no particular order.
One of the nice things about sci.electronics.design is that it's widely redistributed by archive sites, some of which you can also use for posting, which is good since Google Groups no longer links to Usenet.
Some examples:

This is pretty small, because it has to be--those are microwave transistors, and will oscillate at the slightest provocation. The axial resistors and TO-92 parts are all for biasing---the actual amplifier is the part between the output coupling cap (the small orange thing in the middle) and the photodiode, which is the white square with the black middle at the right.
As discussed in medium-gory detail in this paper, laser noise cancellers can let you do shot-noise limited measurements at baseband with lasers that are as much as 70 dB noisier than that.
