I'm trying to build an emg sensor circuit but i wont get ready made amplifiers. has to be made with bjts or mosfets really basic elements this is really important.
i know that it has two high impedence amplifiers and a differential one followed by filters..
but will this be feasible .. i couldn't find lots of resources online... so any help is appreciated.

Why? Is this homework?

no .. it's just a project .. i have to design some kind of amplifier and found that audio amplifiers are really easy and everyone has done it before.

 

Please define emg.
