This web-based calculator helps you design single-stage transistor amplifiers / buffers using either the common emitter or common collector configuration.

It automatically computes key resistor and capacitor values based on your inputs, suggests nearest standard components, and estimates frequency response, gain, and signal swing limits.

The goal is to provide a quick and educational way to prototype audio-frequency amplifier circuits with realistic transistor behavior.

Use the visual plots and export options to support your learning, documentation, or experimentation.
