Depending on the signals being processed, different equivalent circuits are used:
A (shema zameshhenija) is a theoretical model that replaces a complex transistor with simple electrical components like resistors and current sources to make circuit analysis and design easier. 1. Types of Analysis shema zameshhenija tranzistora
: Used to find the operating point (Q-point). The transistor is modeled as a diode (base-emitter) and a constant current source (collector-emitter). Capacitors are treated as open circuits. Depending on the signals being processed
