Low Bit-Depth ADCs for Multi-bit Quanta Image Sensors

IEEE Journal of Solid-State Circuits, 2021
A 1024 $\times $ 896 test chip is presented in this article to explore a low-power readout circuit for a multi-bit quanta image sensor (QIS). Five well-known analog-to-digital converter (ADC) approaches [flash, pipeline, successive approximation register (SAR), cyclic, and single-slope (SS)] are studied, and two types of ADCs, namely, SAR ADCs ...

Image Reconstruction for Quanta Image Sensors Using Deep Neural Networks

2018 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2018
Quanta Image Sensor (QIS) is a single-photon image sensor that oversamples the light field to generate binary measurements. Its single-photon sensitivity makes it an ideal candidate for the next generation image sensor after CMOS. However, image reconstruction of the sensor remains a challenging issue.

Single-Electron Quantization of Dark Current in Quanta Image Sensors

Physical Review Letters
We present a first experimental study of dark current in a quanta image sensor (QIS) based on complementary metal-oxide-semiconductor (CMOS) technology. With the extremely low noise levels of this sensor it is possible to observe spatial and temporal dark current quantization.
