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). Webphase shift is zero. Additional negative feedback is provided to set loop gain to unity at the oscillation frequency, to stabilize the frequency of oscillation, and to reduce harmonic distortion. 18 AN-20An Applications Guide for Op Amps SNOA621C– February 1969– Revised May 2013 Submit Documentation Feedback
