SiGe异质结双极晶体管频率特性分析

Abstract

Abstract: The main factor influencing the frequency property in SiGe HBT is the delay times during carrier transportation. Based on the analysis of the carrier transportation and distribution, the time constant models with clearly physical meanings are proposed. Themodels reveal the relationship between the time constants and the parameters of device structure and the current density in SiGe HBT. The base extending effect is also taken into account in these models. Also, the relationship between f_Tand the parameters of device structure and the current density is analyzed and discussed.

Key words: SiGe HBT, time constant, model, cut-off frequency

CLC Number:
