Quality Factor calculation
as I know the quality factor definition is energy stored/energy dissipated.
i found two formula to calculate it and got the same result
1. -Im(y11)/Re(y11)
2. Im(1/y11)/Re(1/y11)
Is there any relation between these two formulas?
and some other using impedance z to calculate it, is it just because series or parallel that matter ?
Thank You
After stripping all essential informations from a formula, it becomes meaningless.
what does that mean?
I just want to know how the two formula can work.
The essential information would be: y11 of which circuit? Both formulas are probably correct, but for different circuits. As we are not in a guessing game, you should disclose the related circuits.
oh, Thank you for reply FvM,
I am working on a integrated inductor.
Isn't the q factor the same to the circuit?
If y11 describes the inductor admittance, then only the second expression is correct, I think. It corresponds to Q = XL/RL
yes, but my point is the first and the second expression will give you the same answer. I think there is a connection between these expression...
Which formula is for calculate Q factor of capacitance？ And which is for inductance？
Thank you！
