This circuit outputs the peak voltage of the input. The capacitor stores the current peak voltage. If the input voltage is greater, the op-amp's output goes positive until the capacitor charges to the new peak value. If the input voltage is lower, the diode prevents the capacitor from discharging. The second op-amp acts as a buffer. Click the reset switch to discharge the capacitor and reset the peak value to zero.
