The book "A Simulation Case Study Of Semiconductors For Advanced Processors" offers a comprehensive analysis of the electrical properties of bipolar transistors, particularly using Gummel plots to examine the amplification of the structure. A small signal model approach using scattering parameters is pursued to highlight the high-speed aspects. The results show an amplification of about 200, indicating low leakage currents in the structure. The Gummel plot illustrates the relationship between the currents and the base-emitter voltage in a common emitter configuration. This study is particularly relevant for the development of advanced processors and integrated circuits that must meet high-speed requirements.
