Spad fill factor
Web2. mar 2024 · The TG design achieved a fill-factor of 28.6%, and at an excess voltage of 300 mV, it achieved a peak photon detection efficiency of ~2.1% at 440 nm, <1% afterpulsing probability for hold-off times >22 ns, and <200 ps timing jitter. Published in: IEEE Sensors Journal ( Volume: 21 , Issue: 10 , 15 May 2024 ) Article #: Page (s): 12092 - 12103 For a single SPAD, the ratio of its optically sensitive area, A act, to its total area, A tot, is called the fill factor, { { {1}}}. As SPADs require a guard ring [1] [2] to prevent premature edge breakdown, the optical fill factor becomes a product of the diode shape and size with relation the its guard ring.
