Simulation & modeling of CMOS image sensor

Image sensor is the key component in Remote sensing payload, and the primary component of the image sensor is the indirect band gap semiconducting material. In an indirect band gap semiconductor, the maximum valence band energy occurs at a different value of momentum in the conduction band energy. Modeling of the indirect band gap semiconductor (silicon) involves iterative methods of numerical solutions to converge the continuity equation. Continuity equation in physics is an equation that describes the transport of a conserved quantity. Since mass, energy, momentum, electric charge and other natural quantities are conserved under their appropriate conditions; a variety of physical phenomena may be described using continuity equation. To analyze the physical quantities involved in the continuity equation of electric charges, various numerical analysis methods were studied and analyzed. Numerical analysis is the study of algorithms that use numerical approximation for the problems of mathematical analysis.
