　　内容简介：

　　In recent years, the millimeter-wave (mMW) and terahertz (THz) frequency bands (30 - 3000 GHz) has (re)emerged as a promising frequency spectrum for a variety of potential applications in wireless communications, remote sensing, security screening, industrial monitoring, biomedical and chemical spectroscopy, to name a few. The current enthusiasm in mmW/THz has largely been promoted by the rapid scaling of modern semiconductor integrated circuit processes, particularly CMOS and SiGe, which promise low barrier-to-entry mmW/THz systems. On the other hand, the aggressive scaling has generally resulted in a lower supply voltage and breakdown voltage, limiting the amount of power that can be generated. In this talk, we will review classical theories and present recent progresses in our research group on state-of-the-art mmW/THz signal generation and amplification. In particular, we will demonstrate design and optimization strategies for high-efficiency oscillators working close to the maximum oscillation frequency FMAX of the underlying process with record-breaking power and efficiency performances. In addition, we will also discuss the application of these design techniques to high-speed chip-chip interconnect using micromachined dielectric waveguides.

　　主讲人简介：

　　Prof. Xiaoguang “Leo” Liu received his Bachelor’s degree from Zhejiang University in 2004 and PhD degree from Purdue University, USA in 2010. He joined the Department of Electrical and Computer Engineering, University of California, Davis in Nov. 2011 as an assistant professor and was promoted to an associate professor in Jul. 2017. At UC Davis, his research group is investigating various aspects of cutting-edge high-frequency circuit and system design and implementation concepts. Besides typical duties inside the University and professional societies, Dr. Liu has consulted for a number of companies and national labs on topics related to high-frequency circuits, antennas, and systems.
