Electromagnetic interference (emi) evaluation system for image sensors

An apparatus configured to measure electromagnetic radiation coupled from an image sensor integrated circuit (IC) to a nearby cell phone antenna, comprising:

• an image sensor printed circuit board (PCB) having attached thereto on a first side of the image sensor PCB the image sensor IC, the image sensor PCB comprising at least one image sensor decoupling capacitor disposed on a second side of the image sensor PCB different from the first side of the image sensor PCB, the image sensor PCB disposed within a shielding box;
• an image processor PCB including an image processor IC disposed on a first side of the image processor PCB, the image processor PCB having at least one image processor decoupling capacitor, the image processor IC being electrically coupled to the image sensor IC on the image sensor PCB;
• the image processor IC being located outside the shielding box, and
• the at least one image processor decoupling capacitor being disposed within the shielding box.
