Abstract
A wideband digitally-controlled oscillator (DCO) is provided. The wideband DCO includes an active element which is driven by a first digital control signal; a single inductor which is connected to the active element in parallel, and comprises fixed inductance; and a plurality of capacitors which are connected to the single inductor in parallel, and vary operating frequency by being selectively turned on or off by a second digital control signal. Accordingly, the wideband DCO capable of operating in a wideband frequency range using a single inductor is provided, and if the wideband DCO is implemented using a single integrated circuit (IC) chip, the size of chip is reduced as the single inductor is used.
