the end he managed to get the FET circuit to be better than
the light bulb, but it took a lot of work (and probably wasn't worth it).
No. His initial attempt with a FET didn't perform all that well (if
memory serves), but in the end his very complex circuit with (I think)
three high-end opamps and an LED-driven photocell did end up
outperforming the incandescent lamp design.
That's a fascinating read; I'll try to find a pointer if you're
interested. (I have the saga in a paper book, "Analog Circuit Design:
Art, Science, and Personalites", one of my favorite books)
YEs, a great book. Along with Bob Pease's book ('Analog circuit
troubleshooting' or soemthign like that). Well worth reading.
