My
interests are on-die power conversions, power integrity, smart power ICs, and
analog circuits for applications in power electronics and telecommunications.
My
advisors are Professor Seth R. Sanders
and Professor Elad Alon. I
got my B.S. Degree and M.S. Degree in Electrical Engineering from Hanoi University of Technology, I
enjoyed working experiences with Institute
of Material Science (IMS), VAST, Vietnam, JDA
Technology Company, Korea, and the circuit and power groups in Sun
Microsystems, AMD
and Intel lab, as well as previous projects with LG Electronics and KEC of Korea. Current projects
09/2007 ~ now, in UCB Experiences
05/2009
~ 07/2009, Intel, Beaverton, OR, USA –

05/2008 ~ 08/2008, in
Sun Microsystems, Santa Clara, USA – Power integrity for high-performance
microprocessors
09/2004 ~ 04/2007, in KAIST and JDA – Power supply for AM-OLED LCDs
10/2002 ~ 06/2004, in IMS, VAST,
o
DC Power Supply series: 2 modes
– manual (0 - 30V/2A and 0 – 60V / 250mA) and programmable (0-10V precisely
and 0 – 60V), w/ current limiter o
Giant Magneto Impedance (GMI) Measurement System, applied in
HUT o
