  • Automation of the zero-pole identification methods for the stability analysis of microwave active circuits
    Patent number: 8407637
    Abstract: A method of analyzing electrical stability of an active circuit splits a frequency response of an electrical or electronic circuit according to sub-bands (134, 136, 138) and in each sub-band (134, 136, 138) implements a step of determining an identification transfer function adapted for a stability analysis. The step of determining the transfer function is automatic and executed in the form of an identification loop, parameterized according to a current order of transfer function, and stopped when the norm of a phase error function for the error between the phase (222, 224, 226) of the current identified transfer function and that of the frequency response has exceeded a predetermined phase error threshold value.
