I'm researching Division circuits to divide an input voltage of between approx. 0.1 to 10V by a reference voltage of approx. 0.8V. The planned circuit is part of an RMS to dBu converter.
There's a standard 4x op amp 4x transistor circuit in some of the major app notes and Walter Jungs op amp book but I've also been reading about quadrant multipliers.
Firstly - is it possible that division can be performed with a one quadrant multiplier?
Secondly - can anyone point me to some schematics for a one quadrant multiplier? Most of my books jump straight to four-quadrant,
I'm looking for transistor/op-amp circuits - not dedicated ICs please.
Thanks.
