摘要
A 1/f(3) phase noise corner frequency of approximately 1 MHz has been observed in phase noise measurements of single-ended ring oscillators in a 0.18mum CMOS process. Consequently. increased loop bandwidth is necessary for PLLs in a deep submicron CMOS process to minimize jitter contributed by the VCO. As a guide to design. the time domain figure-of-merit kappa is measured as a function of channel width. length. and inverter stage delay.
