Abstract
Silicon-based phototransistors have broad application prospects in the fields of high-frequency communication
automatic control
and power systems. From the perspective of system verification and simulation
there is an urgent need to establish an equivalent circuit model of phototransistors
which needs to include electrical and optical characteristics. This paper proposes a SPICE equivalent model of high-frequency(100MHz~1GHz) silicon-based phototransistors
including the main photoelectric characteristics of the device
and the extraction method of key electrical and optical parameters in the model is established by TCAD simulation. Based on the established SPICE model equivalent circuit of the high-frequency phototransistor
the simulation results can fully describe the electrical and optical characteristics of the phototransistor
it shows that the SPICE model and parameter extraction method proposed in this paper have reference value for system simulation based on high-frequency phototransistor.
