Abstract: This talk presents a focused overview of mm-wave power-amplifier (PA) designs in silicon, including design fundamentals, advanced PA architectures, and state-of-the-art design examples. The talk will start with an introduction of PA performance metrics and their impacts on wireless systems. Next, it presents the design fundamentals of PA active devices and passive networks as well as power combining strategies. The tutorial discusses advanced PA architectures, including Doherty, Outphasing, and Hybrid PAs, for high efficiency, linearity, and bandwidth. Antenna-PA co-designs are covered as well to achieve on-antenna power combining, active load modulation, and reconfiguration. Further, advance and challenges of high mm-Wave PAs will be covered to address the emerging beyond-5G/6G applications. Finally, the talk will conclude with several state-of-the-art mm-wave PA design examples.
Bio: Hua Wang is a full professor and chair of electronics at Department of Information Technology and Electrical Engineering (D-ITET) of Swiss Federal Institute of Technology Zürich (ETH Zürich). He is the director of the ETH Integrated Devices, Electronics, And Systems (IDEAS) Group. Prior to that, he was an associate professor with tenure at the School of Electrical and Computer Engineering (ECE) at Georgia Institute of Technology, USA. He held the Demetrius T. Paris professorship at School of ECE at Georgia Tech. He was the founding director of Georgia Tech Center of Circuits and Systems (CCS) and the director of the Georgia Tech Electronics and Micro-System (GEMS) lab. He worked at Intel Corporation and Skyworks Solutions from 2010 to 2011.
