Abstract

This paper presents a photodetector cell model hierarchically implemented in SpectreHDL. A typical photodiode electrical model is used and Gaussian distribution of the light spot through the pixels of the cell is implemented to estimate the amount of light power each photodiode receives. Light spot movement is also implemented in the photocell model to allow designers the validation of their signal processing circuitry. The model introduced here shows how analog hardware description languages can be used to combine different discipline systems in one model.
