i want to design an opamp multiplier that could multiply two input voltages, i know how to design a summing , differtiator, integrator amplifier but don't know how to design a multiplier,
i just want to know how to start designing an amplifier ???
what should be the first step how to start :/ i am totally confused

this is very hard to understand as i am a beginner, i want to know how to start designing a multiplier , what should be the first step ?

The first step in design is ALWAYS to gain understanding of the operation of the circuit you want to build.

If you can't understand it - you can't design it. The best you can do without understanding is to copy a design and build it.

i understood all the circuits i mentioned in my first post but i wanna know how to design my own circuits like how to write the equations ?

for if i want to design an opamp that can square the input signal what can i do ??
