The source-to-load voltage transfer $A_v$ is found as:
\begin{equation} A_{v}=- \frac{C_{A} R_{B} R_{\ell} s}{\left(R_{\ell} + R_{o}\right) \left(0.5 C_{A} R_{B} s + 1\right)} \end{equation}$- \frac{C_{A} R_{B} R_{\ell}}{R_{\ell} + R_{o}}$

$R_B$ causes a high-pass transfer. The frequency of the pole should maximally equal the minimum frequency of interest $f_{min}$. From that we obtain the design equation:
\begin{equation} f_{min}=\frac{1}{\pi C_{A} R_{B}} \end{equation}From this we obtain:
\begin{equation} R_{B min}=5.053 \cdot 10^{6} \end{equation}Go to RB_Bandwidth_index
