Abstract

Aspects of this disclosure are directed to, DCO circuits and methods. The DCO, comprise: an inductance-capacitance, (LC), resonant circuit having a first branch connected in parallel with a second branch, each branch comprising a capacitor and an inductive-element connected in series with the capacitor; a first transistor connected, by its main terminals, across the capacitor of the first branch; a second transistor connected, by its main terminals, across the capacitor of the second branch; and a biasing current source arranged and connected to provide current to the resonant circuit; wherein a control terminal of the transistor of each branch is connected to a node between the respective capacitor and respective inductive-element of an opposite branch, and wherein at least one of the first transistor and second transistor is controllable to adjust a transconductance of the respective branch.
