Signal processing/CMOS integrated circuit technologies for ultra-compact 3D depth-imaging systems
There is a strong demand to reduce both the cost and size of 3D depth-imaging systems, including LiDAR, for use in ADAS, drone, and precise-motion robotics applications.
We are seeking a Fellow with an innovative idea and the passion to realise the potential of long-range solid-sate LiDAR.
Description of Research
The aim of this programme is to demonstrate the proposed idea through optimized design, implementation and evaluation of the system by using the design-to-production flow of TOSHIBA original photonic-device-mixed CMOS and MEMS processes.
Required Knowledge and Skills
Candidates should possess expertise in (1) signal processing or (2) integrated circuit design for imaging system (ex. CMOS image sensor, ToF camera, certain depth sensor).
(1) RTL design, system design and evaluation using FPGA, MATLAB, C, and python
(2) CMOS integrated (Mixed-Signal) circuit design, andexperience of Cadence Tools.
