Abstract Details

2017, Master of Science in Electrical Engineering (MSEE), Wright State University, Electrical Engineering.
This thesis explores a novel detection architecture for use in a Direct-Detect Flash LIDAR system. The proposed architecture implements detection of the last two surfaces within single pixels of a target scene. The novel, focal plane integrated detector design allows for detection of objects behind sparse and/or partially reflective covering such as forest canopy. The proposed detector would be duplicated and manufactured on-chip behind each avalanche photodiode within a focal plane array. Analog outputs are used to minimize interference from digital components on the analog input signal. The proposed architecture is a low-footprint solution which requires low computational post-processing. Additionally, constant fraction discrimination is used to mitigate range walk. The proposed architecture is designed in 90nm CMOS technology. The footprint is 170.1 µm² with the largest transistor dimension being 22 µm. The design is easily expandable in hardware to allow additional surfaces to be detected.
