A wideband LC-VCO IC with an Inversion-MOS (IMOS)-based novel varactor is proposed in this article. The novel varactor that consists of an IMOS and a fixed metal-insulator-metal (MIM) capacitor is able to provide a continuous tuning range with a single analog control voltage. The proposed VCO IC is designed, fabricated, and fully evaluated on the wafer in 40-nm CMOS SOI. The proposed wideband VCO IC has exhibited a tuning range of 40.3% from 4.14 to 6.23 GHz and a measured FoMT of-197.3 dBc/Hz under a supply voltage of only 0.34 V.
