Transistor Amplifiers: Comprehensive breakdowns of Common Emitter, Common Base, and Common Collector configurations.

Problem Example: Design a voltage divider bias circuit for a 2N3904 transistor to have ( I_C = 2 \textmA ) with ( V_CC = 12V ). Manual Solution: Step-by-step selection of ( R_1, R_2, R_C, R_E ), verification of stability factor S, and Q-point calculation.
