Abstract:

The self-interference (SI) channels in full-duplex (FD) radios have large nano-second-scale delay spreads, which poses a significant challenge in designing SI cancelers that can emulate the SI channel over wide bandwidths. Passive implementations of high delay lines have a prohibitively large form factor and loss when implemented on silicon, whereas …

Abstract:

This article proposes a gallium nitride (GaN)-based isolated silicon carbide (SiC) MOSFET gate driver with an on-chip metal–insulator–metal (MIM) capacitor that has high data rate and low propagation delay. The improved common-mode transient immunity (CMTI) envelope detection technique eliminates the common-mode current ( $I_{mathrm{CM}})$ to improve …
