Gain before feedback simualtion

WebThis method for finding loop gain cannot be used directly in SPICE, because breaking the feedback loop changes the operating point, and the loading effects modeled by Z in in … WebDec 22, 2024 · There are two open loop gains in an amplifier (this may surprise some). One is the "intrinsic" open loop gain which is extracted from the Vout=A (Vinp-Vinm) but the other is due to an attenuated signal which arises from the feedback resistor impedances and the amplifier input impedance.

WebAug 9, 2024 · The Loop Gain simulation of Figure 3 is in fact showing 185degrees around the loop at LG=0dB at 170Mhz – very near the closed loop response peaking of Figure 1. This LG simulation has confirmed the simple circuit of Figure 1 is in fact unstable. WebMar 5, 2003 · The point at which feedback occurs is effected by numerous variables, including atmospheric conditions (temperature, humidity, etc.) so it’s not something that anyone considers an objective measure of performance. Instead the phrase is used to state relative differences: “By adjusting the EQ I was able to get ‘more’ gain before feedback.” headphone mark on head https://cfcaar.org
