Ye, Le is an associate professor in the Institute of Microelectronics, School of EECS. He obtained his B.Sc. from Physics Department of Nanjing University in Nanjing, Jiangsu Province, China, in 2005, and Ph.D. from School of EECS in Peking University, Beijing, China, in 2010, respectively. His research interests include RF & analog IC design, TFET based ID design, IC and system for IOT, and micro integrated system for implanted medical device.

Dr. Ye has published more than 30 research papers, and most of them are published in top-tier conferences and journals, such as JSSC, TCAS-I, EDL, TCAS-II, IMS, A-SSCC, ESSCIRC, ISCAS, and so on. He has applied over 30 patents and owned over 10 patents.

Dr. Ye has more than 6 research projects including NSFC, 02 Major projects, etc. His research achievements are summarized as follows:

1) Ultra-low power analog baseband integrated circuits techniques: proposed ultra-low power, and highly reconfigurable operational amplifiers and analog baseband, which significantly reduce the power, realize the general goal for multimode / multiband wireless communication transceivers, and universally suitable for wide frequency range from narrow bandwidth to ultra-wide bandwidth, and suitable for the advanced process technology, and successfully applied in several wireless communication transceivers.

2)  UHF RFID reader transceiver chip design: proposed the CMOS on-chip transformer-based directional coupler with tunable isolation and frequency to achieve the best isolation level in CMOS on-chip domain, made systematic and complete analysis on the issue which deteriorates the sensitivity in UHF RFID reader transceiver and gave the systematic and complete solution, implemented the CMOS single-chip UHF RFID reader transceiver; such researches significantly alleviate the problem of the interference of the same frequency between transmitter and receiver, significantly improve the isolation between transmitter and receiver, the sensitivity, and the integration, where the isolation is the best in the world.

3)  CMOS millimeter-wave IC design: do the research of CMOS millimeter-wave frequency synthesizer chip with the proposed cascade quarter frequency multiplier , which greatly reduces the power and phase noise.

4)  TFET based IC design: research the new circuit topologies based on the novel device—TFET, and firstly in the world make a systematic and complete analysis on the advantage region of TFET compared with CMOS, and research the TFET based MCU design with ultra-low power, especially ultra-low leakage power for the future IOT applications
