Transfer Function

$$ V_{out} = \begin{cases} G \cdot V_{in} & \text{if $\> V_{ctrl} < V_{ref}$} \\ -G \cdot V_{in} & \text{if $\> V_{ctrl} > V_{ref}$} \\ \end{cases} $$

Analog Resource Usage

$$ \begin{array}{|c|c|} \hline \text{Opamps} & \text{1 of 8} \\ \hline \text{Comparators} & \text{1 of 4} \\ \hline \text{Capacitors} & \text{2 of 32} \\ \hline \end{array} $$
