Abstract

In an embodiment, a voltage-controlled oscillator circuit includes a gain element and an LC resonator coupled with the gain element, the LC resonator including an inductor section and a capacitor section. The capacitor section has at least two branches connected in parallel and a voltage control input for tuning the LC resonator. Any of the at least two branches is selected from the group of DC-coupled and AC-coupled. Characteristics of the two branches and bias voltages of the AC-coupled branches are selected to provide a tuning curve of the voltage-controlled oscillator circuit that is approximately linear.
