Common Emitter Amplifier Simulation (LTspice)

This project demonstrates the design and simulation of a BJT common emitter amplifier using a 2N3904 transistor. The circuit includes proper biasing (voltage divider), coupling capacitors, and an emitter bypass capacitor to achieve voltage amplification.

The input is a 10 mV sinusoidal signal at 10 kHz, and the output waveform shows a significantly amplified signal with phase inversion, which is a key characteristic of common emitter amplifiers. Simulation results also highlight the gain and frequency behavior of the circuit.

This work reflects my ability to design, simulate, and analyze analog electronic circuits, as well as interpret waveform results to evaluate system performance.
