Abstract

This paper presents a low-voltage and low phase noise LC-VCO IC with simplified noise filtering in 180-nm CMOS technology. The novel VCO IC includes a cross-coupled pMOSFET pair, an LC resonator, buffer amplifiers and a tail inductor for noise filtering. The novel and conventional LC-VCO ICs are designed, fabricated and fully tested on wafer. At a power supply voltage of only 0.5 V, the novel VCO IC has exhibited a phase noise of -119.4 dBc/Hz at 1 MHz offset from the 2.25 GHz carrier frequency, which is 2.6 dB better than the conventional one.
