摘要

This paper presents an LC voltage-controlled oscillator (VCO) design which utilizes a set of Inversion-MOS (IMOS)-based varactors. The varactor set is switchable by using a transmission gate such that the tuning range can be extended. The proposed VCO is designed, implemented, and fully evaluated on the wafer in 180-nm CMOS technology. The experimental results show that the VCO has a tuning range of 18.6% from 2.15 to 2.59 GHz. The measured FOMT of-185.2 and-183.2dBc/Hz is achieved when the switches are turned on and off, respectively. The VCO core consumes 6. S9mA at the supply voltage of 1.8V, including the bias current of the IMOS-based varactor set.
