A 12 GHz low-jitter LC-VCO PLL in 130 nm CMOS

Abstract

We present a wideband low-jitter LC-VCO phase-locked loop in 130 nm CMOS technology for high speed serial link applications. The PLL covers a 5.6 GHz to 13.4 GHz frequency range by using two LC-VCO cores with an RMS jitter of 370 fs. The single event effects testing is performed with a neutron beam at Los Alamos National Laboratory and no frequency disturbance is found over the test period. The PLL consumes 50.88 mW of power under a 1.2 V power supply.
