Gate Voltage Effect on Pulse Detection Efficiency of Perimeter-Gated SPADs
Hunter Guthrie, Md Sakibur Sajal, Zexi Liu +1
Perimeter-gated single-photon avalanche diodes (pg-SPADs) are known for their dynamic dark noise modulation capabilities. They are reported to trade noise for photon sensitivity un…

Direct Time-of-Flight Measurement Accuracy Improvement With Perimeter-Gated SPADs
Md Sakibur Sajal, Hunter Guthrie, Zexi Liu +1
Direct time of flight (dToF) measurements are susceptible to errors because of system-level and circuit-level timing jitters. In addition, device-level uncertainty stemming from th…

Bias Variation Compensation in Perimeter-Gated SPAD TRNGs
Md Sakibur Sajal, Hunter Guthrie, Marc Dandin
Random number generators that utilize arrays of entropy source elements suffer from bias variation (BV). Despite the availability of efficient debiasing algorithms, optimized imple…
