Does Eldo RF support Phase Locked Loops?
A – Yes, Eldo RF supports the analysis of phase locked loops described at the transistor level. A dedicated algorithm handles specifically PLLs. The algorithm computes the steady sate solution (i.e. the locked sate waveforms), and the closed loop non linear phase noise. The algorithm supports integer-N PLLs with full SPICE netlists, and possibly fractional PLLs if the divider is modeled with the frequency divider macro-model. The algorithm also reports the individual contributions of the building blocks to the global output phase noise.
