Modeling and simulation of a hybrid 3D silicon detector system using SILVACO and Simulink/MATLAB framework

In this paper, a system of a hybrid pixel detector has been developed. The purpose is to create a flexible and reliable model that simulates the entire system, starting from a 3D detector to a data acquisition system and processing analysis. The model flexibility is achieved by minimizing interdependencies among its entities, so they can be added or removed as needed. The implementation of the system is accomplished using SILVACO and Simulink/MATLAB. The 3D detector is simulated using SILVACO to investigate its electrical performance. It is designed such that to have a good charge collection efficiency, position resolution and reduced charge sharing effects. Simulink is used to implement the readout circuit. The front-end readout circuit includes the Charge Sensitive Amplifier (CSA) and Active Shaper. The most suitable approach and parameters for a real system are selected according to the simulation results. Additionally, practical design constraints are also included in the model.
