Lstb analysis cadence

WebWhat is STB analysis in cadence? The Spectre STB analysis provides a way to simulate continuous time loop gain, phase margin and gain margin without breaking the feedback loop. In the stability analysis you are required to choose a probe from which the loop gain measurements are taken. A setting of CMDM = 1 selects the common-mode gain. … Webanalysis produces inconsistent stability information that does depend upon the type and location of input source [4]. Thus, a general and more accurate approach to perform stability analy-sis is desirable. Bode’s Feedback Theory Bode’s original theory was published in [1] and was later ex-tendedin[6].Inageneralfeedbacknetwork,thequantityofcru-

WebSince an AC analysis produces complex results, the values of real or imaginary parts of complex voltages of AC analysis and their magnitude, phase, decibel, and group delay values are calculated using either the SPICE or Star-Hspice method and the control option ACOUT. The default for Star-Hspice is ACOUT=1.
