A reliable and efficient procedure for oscillator PPV computation, with phase noise macromodeling applications
IEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems
The main effort in oscillator phase noise calculation and macromodeling lies in computing a vector function called the perturbation projection vector (PPV). Current techniques for PPV calculation use time-domain numerics to generate the system's monodromy matrix, followed by full or partial eigenanalysis. We present superior methods that find the PPV using only a single linear solution of the oscillator's time-or frequency-domain steady-state Jacobian matrix. The new methods are better suiteddoi:10.1109/tcad.2002.806599 fatcat:3ng3qhtrkrg7ti2auukqy4rzl4
