Op-Amp

Operational amplifiers are amplifiers that have sufficiently high forward gain so that when negative feedback is applied, the closed-loop transfer function is practically independent of the gain of the op amp. They therefore use two or more stages of gain in order to get high enough total gain.

• Two-stage op-amp
• Folded-cascode op-amp
• High-frequency op-amps
• Low-noise op-amps
• Low-voltage op-amps
