Light Pulse Reception

A light pulse on the photo diode generates a current puls into the pin PD of the device. This current pulse is transformed to a voltage pulse

and amplified. The signal form is dependent on the input pulse width, its slew rate and its strength. The value of the undershoot is als heavily
