Sorry you are right i make a mistake in drawing but in real isn't float, it's like attached photo, and when i put a 100nf capacitor between the stage one and two only the output square wave frequency change and but already oscillate.
Thank you Dear keith;
ok right now i use LT1028 that i found it from some old board, I want to use this amplify for magnetometer too, as i say my coil resistance is about 6 ohms and its Inductance is about 7mh i use two stage Lt1028 with 100Kohm to 50 ohm ratio that about 2000 time so totally...
Hello Dear Keith
Thanks to your Reply, about source impedance it's about 6 ohms (it's a coil) yes you are right but i can't found Low noise amplifier in my area is there any way to do it? is there any source for study about amplify this range of voltage i want to learn more about this.

How I can amplify a micro volts range to volt range?
Which type of op-map i must use?I have very low signal about 1 micro volt and i want to amplify it to about 1 Volts and measure it's frequency it's frequency is in audio range and almost is about about 1-3 KHZ,I use two stage of AD620 IC WITH...
Hi izwirlee_35
Thanks your Attention, I need Send Some GPS protocol DATA Such as GPGGA and some Other data Like MAchine ID to Remote Server Every 5 Seconds not minute.Ok i am trying to do with normal mode.
Thanks alot
Hi izwirlee_35
before i Do the automatic CR+LF Setting but the problem exict, right now when i use
GET **broken link removed** /HTTP1.1
I have Problem as before but when i use like below
GET **broken link removed**
it's ok and i can add data to my log file, in any website and help file said...
