Equivalent circuit

A simplified textbook-style equivalent circuit drawn in black line art on a white background, arranged as a compact reduced small-signal network. The schematic uses only idealized lumped elements and standard symbols, including resistor elements, occasional capacitors or passive branches, independent source symbols, dependent or controlled source symbols, connection nodes, and clearly indicated input and output terminals. The layout is minimal and abstract, cleaner than a full transistor circuit, intended to represent a transformed or approximate amplifier model or reusable equivalent-circuit fragment.
