[sdiy] Analog division

[Karl Ekdahl]

Hi list

So i want to do analog division but i can't really find anything useful, most of what i've found so far are vague statements about being able to do it with a log/antilog approach and then this site; http://en.labs.wikimedia.org/wiki/Electronics/Analog_multipliers which looks great except none of the circuits work when i simulate them. Also i've been looking into using the AD633 but hot damn they're expensive. Any pointers to a fairly accurate (not exceedingly so) division-circuit?

Thanks

Karl
