I'm trying to make a sine wave oscillator with unipolar amplifiers, and all the circuits I find are for bipolar amplifiers. I've tried to modify the bipolar circuit, but it doesn’t work. Can anybody give an idea or a circuit? thank you for your attention.

I want to measure the voltage variations that occur because of the movement of a non-magnetic target near a pot-core coil. where? Let's say on a extreme operating conditions

I have some problems designing the coil of an eddy current sensor. I've been searching for some information in different pages and each of it has some criterion for the desing. I would like to know if anyone knows which criterion must I follow to achieve a successful desing. for any...
