OPerational amplifier:

An Operational amplifier is a DC-coupled high-gain electronic voltage amplifier with adifferential input and, usually, a single-ended output.

Properties of an ideal operational amplifier:

• Infinite input impedance.

• Zero output impedance.

• Zero common-mode gain, or, infinite common-mode rejection.

• Infinite open-loop gain.

• Infinite bandwidth.

• Infinite power supply rejection ratio.

Properties of an real operational amplifier:

• Finite input impedance.

• Finite gain.

• Non-zero output impedance.

• Finite bandwidth.
