Gain and phase plot
WebDec 3, 2024 · You are plotting common mode instead of differential gain, same voltage applied to both inputs. That's why you see negative gain. And your measurement circuit has apparently no provisions to stabilize the operation point, can't see if it is set appropriately. 0 Dec 2, 2024 #3 A astroshey Newbie level 6 Joined Nov 21, 2024 Messages 12 Helped 0 WebNov 23, 2024 · I want to plot the phase-shift versus frequency.

WebThe Gain Margin of the system is the value of the magnitude plot at the phase crossover frequency and Phase Margin is the value of the phase plot at the gain crossover frequency. Gain Margin is the amount gain variation your system can tolerate before going unstable. For example consider a system with 10 d B gain margin at the frequency 15 r … WebFigure 6 shows the gain- and phase response of a 2-pole high-pass filter with varying Q. The transfer function shows that the 180° of phase change can take place over a large frequency range, and the range of the change is inversely proportional to the Q of the circuit. Also note that the shapes of the curves are very similar.
