Designing Low-EMI Switched Capacitor ICs for the IoT (Part 2) (Download)

Circuit designers need to pay close attention to potential electromagnetic-interference (EMI) sources in their design architecture in the early stages of the design phase.

For example, the switched-mode power supply (SMPS), a.k.a power conditioning unit (PCU), is a very efficient source of power for electronic designs. The caveat here is that when the power MOSFETs switch, it will likely become a major source of EMI in the SMPS. Often, this will lead to circuit reliability troubles, especially in spaces like the IoT.
