报告简介：
As self-driving cars and mobile metaverse devices have been developed intensively, LiDAR sensors have emerged because they can offer precise depth images in real time. They employ mainly two technologies; direct time-of-flight (dToF) techniques based on single-photon avalanche diodes (SPAD) support long-range detection and high background resilience, while indirect ToF (iToF) counterparts provide high spatial resolution and low depth noise without a complicated time-to-digital converter (TDC). In this technical seminar, flash LiDAR sensors with three zoom histogramming TDCs (hTDC) combining both dToF and iToF techniques for utilizing their advantages simultaneously are presented. Binary and quaternary searching algorithms are introduced to minimize memory size in the hTDC, and analog counters are employed to realize an area- and energy-efficient LiDAR sensor. The overall architecture, detailed circuit implementation, and measurement results are covered.
主讲人简介：
Seong-Jin Kim received his B.S. degree in Electrical Engineering from Pohang University of Science and Technology (POSTECH), Pohang, Korea, in 2001. He received his M.S. and Ph.D. degrees in Electrical Engineering from Korea Advanced Institute of Science and Technology (KAIST), Daejeon, Korea, in 2003 and 2008, respectively.
From 2008 to 2012, he was a research staff member at Samsung Advanced Institute of Technology (SAIT) in Yongin, Korea, where he engaged in the development of CMOS imagers for the real-time acquisition of 3-D images.
