Hi Analog experts,

I'm studying these slides found in **broken link removed** . You can find this by googling "noise performance of elementary transistor stages".

In the page 10 (Slide number 0410) titled "A resistor also has 1/f noise", I tried to calculate sqrt(dvRf^2) but I got only 70.7n instead of 16n.

I used these numbers to be plugged in that equation.

R=1k, Rs=50, W=1e-6, L=2e-5(calculated), AR=W*L=2e-11, VR=0.1, KFRSi=2e-25, f=1

Could you help me out if I used some wrong number above?

I posted my excel file in **broken link removed**. It should be downloaded, since it's micro soft excel.

Sincerely,
