On-Chip Magnetic Thin-Film Noise Suppressor to Countermeasure Digital Noise from Switching Power Electronic Equipment

Ever-expanding large-scale personal data transfer and rapidly-glowing IoT applications raise mobile communication traffic continuously. Electromangetic harmonics from fast-switching power-electronic inverter equipment, especially driven by SiC or GaN switching devices, generate unnecessary electromagnetic wave that conflicts with telecommunication frequency bands in the GHz range[1]. Accordingly it is expected to develop a new methodology to tolerate the noise suppression and signal integrity of an RF IC.
