NOISE DESCRIPTIONS OF TWOCIRCULAR SYSTEM PLL WITH TRANSFORMATION OF FREQUENCY INTO RING

N.P. Kandyrin
Annotations languages:

The two–ring system of Phase Lock Loops is considered. Expressions for model of spectral density of power of phase noises of such system are received. Results of simulation of noise performances of two-ring PLL for the selected parameters of synthesizable signals are given.
Keywords: two-ring PLL, one-ring PLL, spectral density of power of phase noises
