Abstract
A wide tuning range resonant-mode switchable voltage controlled oscillator (VCO) based on π-type LC network is proposed. By proper configuring the switched negative resistance, the VCO can oscillate at the even mode or odd mode of the π-type LC network, thus the frequency tuning range is greatly increased. The proposed VCO has been implemented in 65 nm CMOS, and achieves a measured tuning range of 39%, from 47.6 to 71.0 GHz. The VCO consumes 10.4mA current from 1.0V power supply, excluding the output buffers. The measured phase noise is -110.3dBc/Hz@47.6 GHz at 10MHz offset.
