Inputs

input Half-Cycle

Outputs

output Continuous

Transfer Function

$$ \frac{\Delta V_{out}}{\Delta t} = \begin{cases} \text{Peak} & \text{if $\> V_{out} < V_{in}$} \\ -\text{Decay} & \text{if $\> V_{out} > V_{in}$} \end{cases} $$

Analog Resource Usage

$$ \begin{array}{|c|c|} \hline \text{Opamps} & \text{2 of 8} \\ \hline \text{Comparators} & \text{1 of 4} \\ \hline \text{Capacitors} & \text{5 of 32} \\ \hline \end{array} $$
