DESCRIPTION:As self-driving cars and mobile metaverse devices have been dev
 eloped intensively\, LiDAR sensors have emerged because they can offer pre
 cise depth images in real time. They employ mainly two technologies\; dire
 ct time-of-flight (dToF) techniques based on single-photon avalanche diode
 s (SPAD) support long-range detection and high background resilience\, whi
 le indirect ToF (iToF) counterparts provide high spatial resolution and lo
 w depth noise without a complicated time-to-digital converter (TDC). In th
 is technical seminar\, flash LiDAR sensors with three zoom histogramming T
 DCs (hTDC) combining both dToF and iToF techniques for utilizing their adv
 antages simultaneously are presented. Binary and quaternary searching algo
 rithms are introduced to minimize memory size in the hTDC\, and analog cou
 nters are employed to realize an area- and energy-efficient LiDAR sensor. 
 The overall architecture\, detailed circuit implementation\, and measureme
 nt results are covered.\n\nCo-sponsored by: Huazhong University of Science

X-ALT-DESC:Description: <br /><p>As self-driving cars and mobile metaverse 
 devices have been developed intensively\, LiDAR sensors have emerged becau
 se they can offer precise depth images in real time. They employ mainly tw
 o technologies\; direct time-of-flight (dToF) techniques based on single-p
 hoton avalanche diodes (SPAD) support long-range detection and high backgr
 ound resilience\, while indirect ToF (iToF) counterparts provide high spat
 ial resolution and low depth noise without a complicated time-to-digital c
 onverter (TDC). In this technical seminar\, flash LiDAR sensors with three
  zoom histogramming TDCs (hTDC) combining both dToF and iToF techniques fo
 r utilizing their advantages simultaneously are presented. Binary and quat
 ernary searching algorithms are introduced to minimize memory size in the 
 hTDC\, and analog counters are employed to realize an area- and energy-eff
 icient LiDAR sensor. The overall architecture\, detailed circuit implement
 ation\, and measurement results are covered.</p>
