The minimum output noise is obtained with all designable noise contributions set to zero.

It is determined by the source noise, receive coil noise, and the receiver gain:

\begin{equation} V_{n Min}=9.634 \cdot 10^{-8} \left(1 + \frac{1.764 \cdot 10^{-7}}{A_{R}^{2}}\right)^{0.5} \end{equation}

From this we obtain a minimum value $A_{Rmin}$ for $A_R$:

\begin{equation} A_{Rmin}=4.046 \cdot 10^{-7} \end{equation}
