Abstract : This paper presents a novel PLL and VCO concept based on the multi-phase direct realignment. A multiphase realigned VCO and PLL operating in the 80-240 MHz frequency range have been realized in 0.18mum standard CMOS process, with a 1.8 V power supply voltage. A comparison between realigned and not realigned PLLs showed a jitter improvement by a factor 2 at 240 MHz without increasing the power consumption, which is 2.4 mW at 240 MHz.
