CAS Hybrid Event | Miniaturised and Passive-Inspired Millimetre-Wave ICs in Silicon Technology by Dr Xi (Forest) Zhu

Circuits and Systems Society

Currently, millimetre-wave (mm-Wave) integrated circuit (IC) design is one of the popular research topics within the IEEE Circuits & Systems Society. As footprints of on-chip passive devices are inherently getting small at mm-Wave region, adopting the classical design approach that is based on distributed elements, such as transmission lines, for on-chip passive components is now fully enabled in standard Silicon-based technology, including CMOS and SiGe.

Consequently, there are opportunities to re-consider how such passive components canbe designed and implemented with active components in a more efficient and effective way. In addition, compared with active components design, it is believed that the full potential of on?chip passive components is still far from being reached.

In this talk, the implementation of miniaturised passive devices as well as the possibility of using such devices to co-design with active components will be discussed. It will be divided into two parts. In Part I, recent works in miniaturised on-chip passive filter design will be presented. Moreover, how to use the passive components to mitigate device-level limitations of silicon will be discussed in Part II.

About the Speaker

Xi (Forest) Zhu received the BEng and PhD in Electronic Engineering from the University of Hertfordshire, Hatfield, UK, in 2005 and 2008, respectively. Since 2016, he has been with the School of Electrical and Data Engineering, University of Technology, Sydney, NSW, Australia. He has authored or co-authored more than 100 papers in international journals and conferences. His current research interests primarily focus on the design of analogue/mixed signal integrated circuits and radio frequency integrated circuits (RFICs) for wireless communication and radar sensing applications.

Dr Zhu was named Australia’s top researcher in the field of Microelectronics and Electronic Packaging (in the discipline of Engineering) by The Australian 2023 Research Magazine. He is an active reviewer for the IEEE Trans. on Circuits and Systems – I: Regular Papers and –II: Express Briefs. Also, he serves as a member of the Technical Review Board for several IEEE journals and conferences, including ISCAS, the flagship conference organized by the IEEE CAS-S. He is also a member of the IEEE CAS-S Analog Signal Processing Technical Committees (ASPTC) and IEEE MTT-S TC-14: Microwave and Millimetre-Wave Integrated Circuits Committee. He has organised and cochaired the special session “Millimetre-Wave Integrated Circuits Design in CMOS and SiGe Technologies” in IEEE International Symposium on Circuits and Systems (ISCAS) 2019. He is currently an Associate Editor of the IEEE Transactions on Circuits and Systems – II: Express Briefs, and IET Microwaves, Antennas and Propagation.
