Abstract
This thesis describes di{uFB00}erent design and implementation techniques for mm-wave phase shifters and power splitters suitable for 5G beamforming applications. A polyphase filter implementation is proposed which achieves wide-band performance without compromising the polyphase filter loss.The proposed polyphase filter is used to design high-performance active phase shifters. Two digitally controlled active phase shifters are designed and fabricated in 45nmSOI CMOS technology. The first design is implemented using a traditional polyphase filter. The second design is implemented using the proposed polyphase filter and can achieve simultaneously low phase error and insertion loss. In addition, this thesis presents a novel fully-integrated N-way Wilkinson power divider/combiner used in 5G beamforming applications.The proposed on-chip Wilkinson power divider is designed using a reduced number of spiral inductors for better integration. As proof of concept, an 8-way Wilkinson power divider is designed and fabricated in 45nm SOI CMOS technology
