Common emitter amplifier with coupling capacitors

Compact single-stage NPN BJT common-emitter amplifier schematic drawn as clean black line art with standard electronics symbols. The transistor is arranged vertically with collector at the top, base on the left, and emitter at the bottom. A collector resistor connects from the collector to the positive supply, and an emitter branch extends downward. The base is fed through an input coupling capacitor from the left, typically with a bias resistor or bias network at the base. The output is taken from the collector through an output coupling capacitor to the right. The overall appearance is a conventional textbook amplifier-stage layout on a white background.
