| Abstract | An electron multiplying CMOS images sensor (emCMOS) enables electron multiplication inside the pixel by the use of high voltage (hv) phase(s) under gate(s). Different possible implementations of hv gates dedicated to impact ionization require specific multiplication patterns and therefore new excess noise formulation. This paper presents a rigorous mathematical approach to the calculation of the excess noise factor for all electron multiplying CMOS pixel structures in the framework of the branching processes and the compounding theorem of the probability generating function. Validation of the model is performed by computing the variance formula for one pixel structure and its corresponding Monte Carlo simulation of the stochastic processes. The signal over noise ratio including the readout noise, SNRro, is introduced to evaluate the possible extreme low light imaging performance as a function of the multiplication parameters. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
