This template from Edrawmax outlines the operational amplifier's crucial stages. It begins with two types of input signals: an inverting input (-) which receives a weak and irregular signal, and a non-inverting input (+). The signals are processed through three primary sections: the Differential Amplifier that amplifies the difference between two input signals, the Voltage Amplifier which amplifies the signal to a higher level, and finally the Output Amplifier that provides a strong and clear output signal. This schematic is essential for understanding signal amplification, a key concept in electronic circuits and systems.
