Abstract

A new multiple-probe method is presented for the simulation of highly nonlinear ring oscillators using the harmonic-balance method. This method is robust compared to the conventional single-probe method and readily converges for a wide range of single-ended and differential ring oscillators. Furthermore, it is computationally more efficient for ring oscillators in which the conventional single-probe method converges
