mulitplying voltages using Amplifiers

[Ams]

Hi,

Can someone suggest a circuit to me that produces an output voltage that is proportional to the product of two inputs.  I have some idea that comparators may be used to achieve the goal. A sketch would be gr8 🙂

Thanks

Ams

Analog devices sells several analog multipliers. One is:

Also see the Wikipedia article on analog multipliers.

In particular the last paragraph on the decline of analog multipliers.
