ASTRACT:
In this talk I will review several research activities in the Harvard Advanced IC Lab. The first topic will be on our latest development of standing wave oscillator design utilizing standing-wave-adaptive tapered transmission lines (SWATT). This structure lowers phase noise through loss-reducing shaping of the transmission line, such that it is adapted to the position-dependent standing wave amplitudes. The second topic of this talk will be on a CMOS/Microfluidic hybrid microsystem for 2D manipulation and detection of biological cells. Combining the power of CMOS chips and the biocompatibility of microfluidic systems, this technology promises to make possible new types of investigations in biomedicine and systems biology, e.g., artificial microtissue assembly. If time permits, I will review quantum THz circuits and mm-wave mode locked circuits that are being actively developed in my laboratory.

BIO:
Donhee Ham received the PhD degree in electrical engineering from Caltech in 2002. From 1997 to 1998, he was with the Laser Interferometer Gravitational Wave Observatory (LIGO). During the summer of 2000, he was with the IBM T. J. Watson Research Center. In 2002, he joined the Faculty of Harvard University as an Assistant Professor of electrical engineering, where his research focus is on RF/microwave/analog integrated circuits, nanostructure imaging, THz quantum circuits, and bio-electronics-microfluidics interface technologies. Dr. Ham ranked first in the Schools of Engineering and Natural Science of Seoul National University (SNU) on graduation and earned the SNU Presidential Top Honor prize. He was a Li Ming scholarship recipient at Caltech during 1999 and IBM Research Fellowship recipient in 2000. He was the winner of the Caltech Charles Wilts doctoral thesis (best thesis) prize in 2002. He is the winner of a 2003 IBM faculty partnership award and shared the Harvard Thomas Hoopes prize for best senior thesis in 2004.
