Characteristics of an Ideal Operational Amplifier (Op-Amp)

- Infinite open-loop gain (Aol): The op-amp amplifies the voltage difference between its inputs by an infinite amount.
- Zero input offset voltage (Vos): There is no output voltage when both inputs are at the same voltage.
- Infinite input impedance (Rin): The op-amp draws no current from its input terminals.
- Zero output impedance (Rout): The op-amp can drive any load without significantly affecting its output voltage.
- Infinite bandwidth (BW): The op-amp can amplify signals of any frequency without distortion.
- Perfect linearity: The op-amp output voltage is directly proportional to the input voltage difference.

Types of Amplifiers

Amplifiers by Configuration

- Inverting amplifier: Inverts the input signal (output is 180° out of phase).
- Non-inverting amplifier: Amplifies the input signal without inverting it (output is in phase).
- Voltage follower: Buffers the input signal with unity gain (output is identical to input).

Amplifiers by Frequency Response

- Audio amplifier: Designed to amplify audio signals (20 Hz to 20 kHz).
- RF amplifier: Designed to amplify radio frequency signals (100 MHz to several GHz).
- Video amplifier: Designed to amplify video signals (50 Hz to several MHz).

Amplifiers by Type of Output

- Class A amplifier: Both halves of the output waveform are amplified (inefficient).
- Class B amplifier: Only one half of the output waveform is amplified (more efficient).
- Class AB amplifier: A compromise between Class A and Class B, amplifying part of both halves of the waveform (moderately efficient).

Other Types of Amplifiers

- Operational amplifier: A high-gain, versatile amplifier often used as a building block in electronic circuits.
- Power amplifier: A high-power amplifier used to drive speakers or other high-current devices.
- Differential amplifier: An amplifier with two inputs that amplifies the difference between the two signals.
- Instrumentation amplifier: A high-input-impedance amplifier designed for use in precision instrumentation applications.
