At the very outset I would like to express my deepest sense of gratitude and profound
respect to my supervisor Professor Dr. Pran Kanai Saha, Dept of EEE, BUET for giving
me the opportunity to work in the field of nanoscale MOSFET. It was his idea on which I
was able to work further and prepare this thesis dissertation. His inspiration and academic
guidance have motivated me to work on development of circuits and systems for medical
application. His feedback from different critical angles has always been encouraging and
useful for my research publications. I would convey my profound respect to my cosupervisor Lieutenant Colonel Md. Tawfiq Amin, PhD, EME of the Department of EECE,
MIST for his guidance throughout the thesis work. His enthusiasm and insight into VLSI
circuit has always brought out the very best in me. In fact, I thank both of them for their
unwavering energy, witty guidance and relentless encouragement which has led me to
become a better researcher.I am thankful to Brigadier General A K M Nazrul Islam, PhD,
Head, Department of EECE, MIST for giving me his valuable time out of his busy schedule
and also for the constructive feedback in my research work. I am also grateful to other
members of the Board of Examiners and reviewers for their invaluable suggestions. I
extend my sincere thanks to all of my course teachers and staffs of EECE department, MIST
for their cordial help and adequate support for successful completion of my research works.
I could never come this far and see so much without the help, love and support of my friends
and colleagues; therefore, I would like to formally thank them all here. I am also grateful
to Maj Md Aminul Islam Sir and my brother Omar Faruque who is one of my department
junior for their relentless help with available software and valuable time. With their
unparallel knowledge in the field of VLSI circuit designing and antenna designing, they
have helped me several times to perform and interpret toughest simulation results.Thanks
to my family who has been there for me through ups and downs. Thanks to my parents for
always believing that I can do anything. Also, I couldn’t found words to thank my husband
and son for their continuous support, sacrifice and understanding throughout the period.
In conclusion, I want to say this thesis is one of the most significant accomplishment in
my life. This surely can be counted as one of the most memorable event in my life so far. I
think this is not just the end here. In fact, this is the new beginning of me as a researcher in
the field of VLSI circuit design. |

Recently, there has been a surge in demand for biomedical devices that can continuously
monitor essential life indicators including heart rate variability (HRV) and breathing rate
etc. This ideal device would be small, wearable, wireless, networkable and low-power,
allowing for vital sign monitoring. The impulse radio-based ultra-wideband (IR-UWB)
technology is a promising technology that can meet these requirements. IR-UWB has
received a lot of attention after Federal Communications Commission (FCC) approved
the 3.1GHz-10.6GHz frequency band in 2002. To represent information, IR-UWB uses
incredibly narrow Gaussian monocycle pulses or any other type of short RF pulse. IRUWB system does not necessarily require carrier signals is one of its most appealing
features. In light of these advantages, this research proposes a new ultra-wide band
(UWB) transmitter system based on impulses with low power consumption and a simple
architecture. The illustrated UWB transmitter consumes low-power and generates a
359.44 mV output pulse swing with a pulse width of 100 ps for the Gaussian monocycle
pulse. Due to its increased output voltage and low power consumption when compared
to other circuits, the given topology is functional and suitable for use in medical
applications and short-range wireless communication.For Ultra-wide band (UWB)
communication applications a low cost, miniature size coplanar waveguide (CPW) fed
ultra-wide band (UWB) antenna is also proposed which is ideal for UWB applications
and has return loss less than -10db from 3GHz to 10.6GHz. To accomplish the UWB
bandwidth, design characteristics have been optimized. The proposed antenna is a simple
coplanar wave guide (CPW) fed aperture antenna where the concept of modified ground
plane is applied to enhance the bandwidth and it is compatible with the designed UWB
transmitter. |
