    How can I find out the causes of the variations of input voltages in my amplifier?

    I'm trying to build a Instrumentation amplifier that would do a 10uV -> 10mVamplification. The motivation is to measure uA currents on a small enough shunt resistor (1-10Ohm). For a proof of concept, I've built a circuit like the one below with a distinction that I'm powering it with two 9V...
