Analog Devices published a book called "nonlinear circuits handbook"
which has chapters
about log circuits, multipliers and divider circuits, RMS circuits,
etc. Unforunately it
appears to be out of print (1976, ISBN 0-916550-01-X).

You may want to try searching www.analog.com for individual chapters
or application
notes. You may be able to find schematics in past issues of the
"Analog Dialogue".

Also check "The Art of Electronics" by Horowitz and Hill ISBN: 0521370957
