Abstract:
While mm-wave imaging for security screening and contraband detection has existed
for many years in III-V technology recent advances in CMOS technology enable the
possibility of low-power, portable and possibly even covert mm-wave imaging systems.
In this exciting and entertaining seminar many new techniques developed at UCLA
towards this goal will be discussed including mm-wave imaging receivers based on
super-regeneration techniques that operate from 200 to 500 GHz in commercial
CMOS technology. Antenna-less regenerative receivers that can achieve sub-fw/
Hz0.5 noise equivalent power, and fully implemented focal plane arrays based on
CMOS imaging receivers will also be discussed. Finally a fully CMOS implemented 3D
imaging radar operating at 144 GHz will be discussed that is capable of capturing 3D
images of objects at several meters of range with centimeter scale resolution.

Adrian is currently a Ph.D. candidate in the department of Electrical Engineering at
UCLA and has a research focus on mm-wave imaging, sub-mm-wave imaging and mm-
wave communications systems.
