Hi guys,
I wanna make a square rooter circuit so that take the square root of a sine wave, The idea is to add some DC-OFFSET to the sine wave so that I have a Completely positive sine wave.
I decided to use op-amps for doing so. I want to take the log of the input signal then multiply the result by a factor of 1/2 and final take the anti log of it. The result would be the square rooting of the input.
Please take a look at the below square rooter circuit and give me your idea.
The main problem which I am dealing with is that I am not sure adding some DC offset to the input and finally removing it by a capacitor at the output will give me the proper signal?
Thanks a lot
