Mathematical function circuit

[pionixstar90]

I'm focusing on the analog circuit.
Is there any data sheet of available mathematical function circuit?
I would like to know what mathematical functions are available in electronics circuit
such as addition, subtraction, multiply, divide, tanh(x), |x| etc. done by the voltage of current.

Thank you very much

Hi Pionixstar welcome from me. I might not be the best qualified member to answer your question, as my maths is not brilliant, having said that i am at a loss as to your data sheet question, there is a fair bit of maths in electronics, probably the most used is ohms law, relations between power voltage resistance etc. there are other mathematical laws, plus plenty of complex formula, i would say grab a book on electronics with equal electronic studys with mathematical back up theory to inforce the practical

Addition (summing) & subtraction are the easiest and are done using simple & (single) op-amp circuits.
Absolute value circuits are called full-wave rectifiers and are also easily implemented with op-amps.
Multiplication & division circuits are more complex and is usually done within special IC's.
Just Google for the different keywords and I'm sure you'll find lots of examples.

Analog Devices is one of the manufacturers who have some analog special function circuits in their portfolio. Have a look at http://www.analog.com/en/special-linear-functions/products/index.html

Thanks you all
I'll looking into it
