  • Abstract
    This paper discusses the MOS differential VCO under tuning situation and shows that the coefficient shifting in the differential equation is another restriction to the tuning range besides the tuning range of the LC tank. In respect of this point of view, a new topology is adopted to breakdown the VCO´s tuning range bottleneck. The simulation result shows that f max/fmin of the new circuit can reach 10.
