Table 1.

The three technologies main comparison points.

Criteria QIS CIS SPADs Matrix
Data Rate 1 5–12 Gb/s 0.3–1 Gb/s 0.1–0.6 Gb/s
Read Noise <0.25 e− r.m.s. >1 e− r.m.s. <0.15 e− r.m.s.
Dark Current/Count Rate 2 0.1 e−/(jot·s) 10–500 e−/(pix·s) 200 counts/(pix·s)
Power Supply 2.5/3.3 V 2.5/3.3/5 V 22–27 V
Single Photon Counting YES NO YES

1 For a device with 2.5 mm2 area size; 2 We define Dark Current for QIS/CIS and Dark Count Rate for SPADs, these values are measured at room temperature.
