A WAFER LEVEL VACUUM PACKAGING TECHNOLOGY FOR MEMS BASED LONG-WAVE INFRARED SENSORS
Demirhan Aydın, Gülşah; Akın, Tayfun; Kalay, Yunus Eren; Department of Micro and Nanotechnology (2022-8-11)
This thesis proposes a new approach to obtain a wafer level vacuum packaging that satisfies the requirements of the thermal sensors at low cost and with high performance. The moth-eye structures are formed on both side of a polished flat silicon wafer without any cavity to allow the transmission of the infrared radiation in long wave infrared region (LWIR). Then, this wafer is bonded to another spacer wafer using Au-In Trans-liquid phase (TLP) approach that allows bonding at low temperature (around 200℃); t...
High-performance readout circuit for resonator-based MEMS accelerometer using digital control loop
Ali, Muhammad; Akın, Tayfun; Department of Electrical and Electronics Engineering (2022-11)
This study proposes a new digital control loop-based compact readout circuit for a resonant MEMS accelerometer providing high performance with reduced temperature and power supply dependence while utilizing low processing power. The readout circuit utilizes a charge-sensing pre-amplifier stage that converts the small motional current to readable voltage, which is then converted to the digital domain using a 16-bit ADC to perform the amplitude and frequency extraction in the digital domain. A Proportional In...
A MULTISCALE MODELING APPROACH TO UNDERSTAND MECHANISM OF DEPOSIT CONTROL BY LUBRICANT DETERGENTS AND DISPERSANTS
Kan, Esra; Yıldırım, Erol; Department of Polymer Science and Technology (2022-7-29)
With the recent developments in high performance computing power, molecular modeling calculations to design and improve new generation additives for engine oils have reached a level that can support and guide experimental results. Control of insoluble nanoparticle aggregations in oil and on the engine pistons is the most important key performance parameter for lubricant oil additives. General consensus about the mechanism of deposit build-up is the self-aggregation of nanosized insoluble structures. Deterge...
Thermal imaging based on mechanical vibrations
Yılmaz, Şener; Azgın, Kıvanç; Department of Mechanical Engineering (2022-8-19)
The thesis proposes a digital, resonance readout method based on a lock-in based digital phase locked loop (DPLL) mechanism, which is designed, simulated, implemented and tested using a Xilinx made Field Programmable Gate Array (FPGA). Implementation is performed using a hardware descriptive language (VHDL) on low level. Certain digital signal processing algorithms such as lock-in detection, DPLL, DDS and CORDIC are implemented, simulated and tested. Moreover, the design is shown to be capable of resonating...
