    A 60mV-3V Input Range Boost Converter with Amplitude-Regulated and Intermittently Operating Oscillator for Energy Harvesting

    A boost converter that has a wide input-voltage range is presented. The wide range is achieved by an oscillator that can start operations at ultra-low input voltages. Moreover, it uses an amplitude regulation circuit to avoid overvoltage problems and implements a power-down circuit to eliminate the unnecessary power consumption. Experimental results showed that the proposed circuit enabled an input range from 60 mV to 3 V and achieved high power efficiencies. To the best of our knowledge, this is the first time that a boost converter supporting a wide input range from sub-100 mV to several volts has been achieved.

    Hong Gao received the B.S. degree from China University of Petroleum, Beijing, China, in 2009, and the M.S. degree from Gunma University, Kiryu, Japan, in 2012. In 2012, she joined Fujitsu Laboratories Limited, Kawasaki, Japan, where she has engaged in research on power integrated circuits. Her current research interests include the applications of power management circuits in wireless sensor networks.

    Dr. Mau-Chung Frank Chang is presently the Wintek Endowed Chair and Distinguished Professor of Electrical Engineering and the Chairman of the Electrical Engineering Department, UCLA.

    Before joining UCLA, he was the Assistant Director and Department Manager of the High Speed Electronics Laboratory of Rockwell International Science Center (1983-1997), Thousand Oaks, California. In this tenure, he developed and transferred the AlGaAs/GaAs Heterojunction Bipolar Transistor (HBT) and BiFET (Planar HBT/MESFET) integrated circuit technologies from the research laboratory to the production line (later became Conexant Systems and Skyworks). The HBT/BiFET productions have grown into multi-billion dollar businesses and have dominated the cell phone power amplifier and front-end module markets for the past twenty years (currently exceeding 10 billion units/year and exceeding 50 billion units in the last decade). Throughout his career, Dr. Chang's research has primarily focused on the research & development of high-speed semiconductor devices and integrated circuits for RF and mixed-signal communication radar and imaging system applications. He was the principal investigator at Rockwell in leading DARPA's ultra-high speed ADC/DAC development for direct conversion transceiver (DCT) and digital radar receivers (DRR) systems. He was the inventor of the multiband, reconfigurable RF-Interconnects for Chip-Multi-Processor (CMP) inter-core communications and inter-chip CPU-to-Memory communications. He was the 1st to demonstrate a CMOS active imager at sub-mm-Wave (180GHz) based on a Time-Encoded Digital Regenerative Receiver. He also pioneered the development of self-healing 57-64GHz radio-on-a-chip (DARPA's HEALICs program) with embedded sensors, actuators and self-diagnosis/curing capabilities; and ultra low phase noise VCO with the invented Digitally Controlled Artificial Dielectric (DiCAD) embedded in CMOS technologies to vary its transmission-line permittivity in real-time (up to 20X) for realizing reconfigurable multiband/mode radios in (sub-)mm-Wave frequencies. He also realized the first CMOS VCO for Terahertz operation (1.3THz) and devised the first tri-color CMOS active imager at 180-500GHz based on a Time-Encoded Digital Regenerative Receiver and the first 3-dimensional SAR imaging radar with sub-centimeter range resolution at 144GHz.

    Dr. Chang is a Member of the US National Academy of Engineering and an Academician of Academia Sinica, Taiwan, Republic of China. He is also a Fellow of IEEE. He has received numerous awards (see later section on awards and recognitions) including Rockwell's Leonardo Da Vinci Award (Engineer of the Year, 1992), IEEE David Sarnoff Award (2006), Pan Wen Yuan Foundation Award (2008), CESASC Life-Time Achievement Award (2009) and John J. Guarrera Engineering Educator of the Year Award from the Engineers' Council (2014). He also received National Taiwan University's Distinguished Alumnus Award (2013), National Tsing Hua University's Distinguished Engineering Alumnus Award (2002) and National Chiao Tung University's Distinguished Alumnus Award (1997).

    Dr. Chang earned his B.S. in Physics from National Taiwan University in 1972, his M.S. in Materials Science from National Tsing Hua University in 1974, and his Ph.D. in Electronics Engineering from National Chiao Tung University and a National Doctor of Engineering Degree, conferred by Ministry of Education, Taiwan, ROC, both in 1979.

    [SSCS Distinguished Lecture] TBD.


    Ullrich R. Pfeiffer received the diploma degree in physics and the Ph.D. in physics from the University of Heidelberg, Germany, in 1996 and 1999 respectively. In 1997 he worked as a research fellow at the Rutherford Appleton Laboratory, Oxfordshire England.

    From 1999-2001 he was working as a Postdoctoral Researcher, at the University of Heidelberg on real-time electronics for particle physics experiments at the European Organization for Nuclear Research (CERN), Switzerland.

    From 2001 to 2006 he was with the IBM T.J. Watson Research Center where his research involved RF circuit design, power amplifier design at 60GHz and 77GHz, high-frequency modeling and packaging for millimeter-wave communication systems.

    In 2007 he received a European Young Investigator Award and lead the THz electronics group at the Institute of High-Frequency and Quantum Electronics at the University of Siegen, Germany.

    Since 2008 he holds the High-frequency and Communication Technology chair at the University of Wuppertal, Germany.

    He was the co-recipient of the 2004 and 2006 Lewis Winner Award for Outstanding Paper at the IEEE International Solid-State Circuit Conference, the co-recipient of the 2006 IBM Pat Goldberg Memorial Best Paper Award, the 2008 EuMIC Best Paper Award, the 2009 Best RFIC Oral Paper Presentation, and the 2010 EuMC Microwave Prize, and the 2012 Jan Van Vessem Award for Outstanding European Paper at the 2012 IEEE International Solid-State Circuit Conference.

    He is a Senior Member of IEEE, and serves on the technical program committee of the International Solid-State Circuits Conference, the European Solid-State Circuits Conference, the Bipolar/BiCMOS Circuits and Technology Meeting, the Silicon Monolithic Integrated Circuits in RF Systems Conference, and the European Microwave Integrated Circuits Conference.

    He has authored and co-authored 100+ publications and has been principal inventor and co-inventor of 10+ US and international issued patents, relating to RF, millimeter-wave, terahertz communication/imaging circuits and sensors.
