Addressing RF Coupling in Wireless SoC System Design (Download)

Wireless system-on-chip (SoC) designs require implementing all circuit domains on the same die. This enables manufacturers to reduce cost and support integrity. On the other hand, crosstalk between these domains can be problematic and degrade the overall performance.

Electromagnetic interference (EMI) is caused by radiated radio-frequency (RF) signals. Various techniques are available to lower EMI in system design. For instance, radiated RF can be addressed with filtering and shielding; however, this doesn’t mitigate on-chip RF coupling.
