Abstract
A phase-locked loop (PLL) that is highly robust to supply/substrate noise is described. A new type of voltage-controlled oscillator (VCO) based on pseudo-differential delay elements is presented. The proposed circuit is implemented using a 0.35 μm CMOS process technology with a 3.3 V supply. It generates 16 clock phases at 250 MHz, tailored to gigabit link applications
