Linearization of non-linear circuits, particularly involving BJTs, is crucial for simplifying complex analyses. By focusing on a narrow range around the operating point, or Q-point, we can derive the small signal equivalent circuit, allowing for easier manipulation of circuit responses. The concepts of transfer characteristics and their linearization form the basis for effective circuit design in analog electronics.

Term: Linearization
Definition: The process of approximating a non-linear function by a linear function in a small neighborhood of a point.
Term: Small Signal Equivalent Circuit
Definition: A simplified model used to analyze the behavior of circuits with small signal variations around a predetermined operating point.
Term: Operating Point (Qpoint)
Definition: The steady-state point of the circuit where it operates linearly and around which small signal analysis is performed.
