  • Abstract
    This paper analyzes the common-mode response of LC voltage-controlled oscillators (VCOs) in DC and periodic steady state regimes. The dependence of the common-mode voltage (vcm) on the oscillation amplitude is theoretically studied. Closed and simple expressions for vcm suitable for the VCO design and optimization are derived. The agreement with transistor level simulations has been verified in a 1.2V low-power 90nm CMOS case of study.
