Transfer Function

$$ \frac{V_{out}(s)}{V_{in}(s)} = \frac{s^2 + \frac{2\pi f_z}{Q_z}s + 4\pi^2 f_z^2}{s^2 + \frac{2\pi f_p}{Q_p}s + 4\pi^2 f_p^2} \\ G_{dc} = G_{hf}\bigg(\frac{f_z}{f_p}\bigg)^2 $$

Analog Resource Usage

$$ \begin{array}{|c|c|} \hline \text{Opamps} & \text{2 of 8} \\ \hline \text{Capacitors} & \text{8 of 32} \\ \hline \end{array} \\~\\ $$
