SPAD-based Light Detection and Ranging for 3D imaging: Receiver operation and in-pixel TDC design for automotive application

In this work, a SPAD-based LiDAR system is studied. In particular, the system employs a direct time-of-flight (dToF) method to reconstruct a target-reflected pulses using histogram, from which the distance to the target is estimated. More particularly, a time correlated single photon counting (TCSPC) method has been used to record the flight...

Design and Fabrication of On-Chip Cooing Devices Based on the Peltier Effect

The aim of this thesis project is to design and fabricate a high efficiency on chip cooling device based on the Peltier effect. Bismuth telluride (Bi2Te3) and antimony telluride (Sb2Te3) are employed to form thermocouple for their high Seebeck coefficient and high figure of merit. The models of the devices are simulated in the software program...
