EMI and EMC Compliance Testing in Smartphone

Rating: 2 votes, 5.00 average.
EMC within electronic components has become an increasingly important issue for embedded designers to contend with. As system frequencies and the need for lower supply voltages increase, the end application becomes more and more vulnerable to the negative affects of EMI. These electrical influences can be generated by either radiated or conductive EMI sources. Radiated sources include anything electrical or electromechanical, including motors, power lines, antennas, traces on a PCB (Printed Circuit Board), and even the silicon components on the PCB. Conductive EMI primarily shows itself as electrical “noise” on the power supply lines of an application and can be caused by induced voltage spikes from other devices within a system.

    At a quick visit, I got quite curious on your article, because I working with a cell-phone based system, but I wonder if you could add information regarding to the tests themselves. By the 1st figure attached, we can see a simulation and some measurements performed, but the picture resolution isn't too clear. Could you elaborate what tools were employed in such a process and what metrics are usually employed ?
