Memo: Op-amp’s gain factor and noise problems

First, here's a quick cheatsheet on closed-loop gain factor for inverting and non-inverting amplifiers. The gain of inverting amplifier isĀ given by the resistance R2 across the feedback loop divided by the resistance R1 across the forward input. A = R2/R1 Meanwhile, the gain of non-inverting amplifier is given by A = 1 + R2/R1 as… Continue reading Memo: Op-amp’s gain factor and noise problems
