Operational Amplifier Basics - Op-amp tutorial

WebYes - sometimes the terms are somewhat misleading. In general, we have three different gain conventions for feedback circuits: Open-loop gain of the amplifier (alone): Aol, Closed-loop gain of the amplifier with feedback: Acl, Loop gain Aloop, which is the gain of the complete loop (to be measured or simulated after breaking the loop at a suitable point). The open-loop gain of an electronic amplifier is the gain obtained when no overall feedback is used in the circuit. The open-loop gain of many electronic amplifiers is exceedingly high (by design) – an ideal operational amplifier (op-amp) has infinite open-loop gain. Typically an op-amp may have a maximal open-loop gain of around , or 100 dB. my help tabernacleWebThe op amp in the noninverting amplifier circuit shown has an input resistance of 400 kΩ, an output resistance of 5 kΩ, and an open-loop gain of 20,000.
