gain

So I am planning to use an AD620 instrumentation amplifier in my circuit. The gain formula is G = 1+(49.4KOhm/Rg), Rg being the deciding resistance value. By that logic if a 100K preset or Pot is set to zero, Gain attempted is (∞ + 1), which besides being impossible is also way above the 10000...

I want you make a amplifier with 500 voltage gain and use a amplifier with common emitter, but I can't get a gain over the 100 with any value of resistors. Vdd is 12 V and b is 100

Can you tell me if my result results are correct, and if there are errors where are they? I used the symbol rms to indicate the root-mean-square, Avo is open-circuit voltage gain, Ap is the power gain, Rl is the load resistance. i stands for input, s for source and o per output. > 1) A sensor...

This post is "picking the brains of smarter than me" more than anything. It's a simple question, but I can't seem to find a consistent answer to it. I have heard sooo many different suggestions and so many different "right ways" of doing this, that every way I try, gives different results...

Hello, I am new to hardware design. I am designing measurement circuit for Impedance Spectroscopy of electrochemistry cell. I need to measure the current coming from electrodes which have range from few milliamperes to few nanoamperes. as literature suggested, the equivalent circuit for...

Hi everybody! Hope you're good! :) I'm strugglin since some days on that nice muscial tool. I've replaced some faulty switches. Replaced them with new one from Mouser. Sadly I've managed to hurt some VIAS connecting both side of the board. Luckilly enough this is just 2 layer board (top/bottom)...
