F-V converter and Ring Mod. stuff

[gstopp at fibermux.com]

     One of the ring mod circuits in the Electronotes PCC that's being 
     mailed around it built around a couple CA3080's. This design uses an 
     inverting VCA and a non-inverting VCA in parallel on the X input, and 
     when the Y input is positive the non-inverting VCA is turned on and 
     when the Y input is negative the inverting VCA is turned on. Plenty of 
     places to add tweaks.

     on the subject of ring modulators, anyone have schematics for a four 
     quadrant multiplier from discrete circuitry (opamps ok)?  I'd like a 
     design that can work at DC, too.
