Hello

i'm planning on build a dc electronic load and i want to make the constant power and constant resistance modes analog so i can just put that in a feedback loop rather than constantly sampling -> making floating point calculations -> outputting through the dac
so i need your help with an analog multiplier/divider circuit/IC whichever possible and whichever you think might be stable in such application.

thanks
 

It's possible with industry standard analog multipliers like AD633. As you are designing a feedback system with variable gain, achieving stability for all operation conditions isn't quite easy, but basically possible at the cost of bandwidth.
