Quanta Image Sensor Jot With Sub 0.3e- r.m.s. Read Noise and Photon Counting Capability

The first quanta image sensor jot with photon counting capability is demonstrated. The low-voltage device demonstrates less than 0.3e- r.m.s. read noise on a single read out without the use of avalanche gain and single-electron signal quantization is observed. A new method for determining read noise and conversion gain is also introduced.
