Characterization of quanta image sensor pixels with deep sub-electron read noise is reported. Pixels with conversion gain of 423μV/eand read noise as low as 0.22er.m.s. were measured. Dark current is 0.1e-/s at room temperature, and lag less than 0.1e-. This is one of the first works reporting detailed characterization of image sensor pixels with mean… (More)
A new quantum random number generation method is proposed. The method is based on the randomness of the photon emission process and the single photon counting capability of the Quanta Image Sensor (QIS). It has the potential to generate high-quality random numbers with remarkable data output rate. In this paper, the principle of photon statistics and theory… (More)
The Quanta Image Sensor (QIS) concept and recent work on its associated jot device are discussed. A bipolar jot and a pump-gate jot are described. Both have been modelled in TCAD. As simulated, the pump-gate jot has a full well of 200eand conversion gain of 480uV/e-.
A new photodetector designed for Quanta Image Sensor (QIS) application is proposed. The photodetector is a backside-illuminated, buried photodiode with a vertically integrated pump and transfer gate and a distal floating diffusion to reduce parasitic capacitance. The structure features compact layout and high conversion gain. The proposed device is modelled… (More)
Early research progress in the realization of the Quanta Image Sensor is reported. Simulation of binary data acquisition and image formation was performed. Initial analysis and simulation of a readout signal chain has been performed and bounds on power dissipation established. Photodetector device concepts have been explored using TCAD. (Invited 1 ) OCIS… (More)

BACKGROUND Recurrent respiratory tract infections (RRTIs) have a negative impact on both children's health and family wellbeing. Deficiency of ZhengQi used to be an instinct factor driving RRTI in Traditional Chinese Medicine (TCM). Our clinical observations suggest that children with gastrointestinal heat retention syndrome (GHRS) may have a greater risk… (More)
The Quanta Image Sensor (QIS) was conceived when contemplating shrinking pixel sizes and storage capacities, and the steady increase in digital processing power. In the single-bit QIS, the output of each field is a binary bit plane, where each bit represents the presence or absence of at least one photoelectron in a photodetector. A series of bit planes is… (More)
Lipid peroxidation can react with free amines of proteins and induce modification of structural and functional properties. This study presents the IgE binding capacity and structural changes of shrimp tropomyosin (TM) under oxidative stress with 4-hydroxy-2-nonenal (HNE). IgE binding capacity was evaluated with the dot-blot assay and inhibition… (More)
The Quanta Image Sensor (QIS) is a possible 3 generation image sensor. A QIS consists of a large array of photodetectors (perhaps a billion) that are capable of sensing a single photoelectron with high SNR. Such a binary output photodetector is called a “jot”. It requires small size (e.g. 500 nm pitch), high quantum efficiency, and very low readout noise… (More)
