Abstract
A photodetector integrated circuit (IC) having an electromagnetic interference (EMI) sensor integrated therein is provided for sensing EMI at the photodetector. Integrating the EMI sensor into the photodetector IC ensures that the EMI sensor is in proximity to the photodetector so that any EMI that is sensed is actually EMI to which the photodetector is exposed. The sensed EMI may then be used for a number of reasons, such as to determine the root cause of damage to circuitry of the system, to determine the point in time at which an EMI event occurred, or to trigger a warning when a determination is made that an EMI limit has been reached.
