Скачать или смотреть BJT AC Analysis

The provided sources outline the fundamental principles of BJT small-signal AC analysis, a process used to model the linear behavior of transistors in various amplifier circuits. Essential modeling techniques such as the hybrid-pi, re, and T-models are detailed, alongside systematic procedures for simplifying circuits by zeroing DC sources and replacing transistors with equivalent circuit models. These texts compare different configurations, emphasizing that common-collector (emitter follower) circuits provide high input and low output impedance, while common-emitter circuits offer moderate values suitable for general use. Technical factors like transconductance, the Early effect, and Miller capacitance are identified as critical elements that influence gain and frequency response. Calculations for voltage gain and impedance are provided for each topology, illustrating how bias points determine a transistor's performance. Ultimately, the materials serve as a comprehensive guide for engineering students to linearize nonlinear devices for practical amplifier design and analysis.
