Integrated Circuit Design for Reduced EMI

Radiation of electromagnetic interference is a problematic side-effect of digital electronic systems. Radiation becomes amplified as it conducts and radiates from an integrated circuit to a PCB and beyond the system. While proficient system level design is paramount for minimizing EMI, the design of the integrated circuits can help to control EMI by minimizing the source of the radiation. Several aspects of typical IC design can be optimized in order to minimize the levels of radiation produce by the device. These aspects include package selection, pin assignments, on-chip module partitioning, power routing, clock distribution, oscillator/clock options, and logic selections.
