Accurate modeling of the circuits at different steps of design process is an essential factor for having a cost effective and high throughput final circuit implementation. In this paper an efficient system level modeling of a Digital Pixel Sensor (DPS) architecture with the capability of harvesting the energy of illuminated light is presented. The SystemC and analog/mixed signal (AMS) extension is used for the modeling. The proposed model mainly focuses on the accuracy of the fabricated photodiode model, a 11Ã11Î¼m2 n+/p-substrate photodiode which is fabricated in a standard CMOS 0.18Â Î¼m technology. This accuracy is important for both light sensing and energy harvesting phases. The model uses electrical linear network (ELN) and timed data flow (TDF) models of computation (MoC) of SystemC-AMS. Simulation results of the proposed model are in good agreement with experimental results of the photodiodes. In order to evaluate the photodiode model in pixel architecture, a system level model of a DPS with capability of harvesting illuminated energy is also proposed and implemented in SystemC-AMS framework.
