Hi Brian --

Ooooops -- we're both on the wrong page!  It's in Ch. 7, p. 393 in the 
second edition.  The part down at the bottom.  Mine is different in the 
details, but still uses the idea of having all switch terminals at 0V.  The 
Ch. 4 circuit is the same principle, but for cap discharge, as in a VCO 
(viz. Rene).

I wish I could find MOSFETs without the stupid protection diodes 
anymore.  Anybody?  I found the nice ALD parts, but they're 10 V max.

I posted a slightly less brief description of this project over at Muff's:


I was just reading my copy of H & H over a hamburger, but it's mentioned in 
chapter 4 of the 2nd edition.
