talking about calculus etc.

[Paul Schreiber]

The best *general purpose*, transistor-level book that explain many circuits
found in analog
synths is:

"Analysis and Design of Analog Intrgrated Circuits - 2nd Edition" by Gray &
Meyer.
ISBN 0-471-87493-0

(there may be a 3rd Edition)

There simply is no such book called "Mysteries of Synth Circuits Explained!"
but the Gray/Meyer
book has the best explanation of current mirrors, diff amps, match pairs,
etc.

Best explanation of Moog filter: read the patent! Extremely detailed. Can
get it for $5 off
the IBM patent server.
