Abstract :
A simple high-performance nonlinear digital PLL is fabricated in 90 nm CMOS with operating range of 0.5 to 3.25 GHz and 1.24 ps jitter. New insights into the PLL behavior are discussed. The classical ldquo20Logrdquo in-band phase noise tracking does not hold for the type of nonlinear digital loops.
