    摘要: 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.

    摘要: A voltage controlled oscillator (VCO) includes a VCO unit having multiple VCO unit output terminals and an amplifier having multiple amplifier output terminals respectively connected to the VCO unit output terminals. The VCO unit generates first output signals having an oscillation frequency corresponding to a supply voltage. The amplifier amplifies a value obtained by performing n-th differentiation on a transconductance component of each first output signal (n being a natural number). Second output signals, corresponding to the first output signals, are output through the amplifier output terminals. Each second output signal includes the amplified value of the corresponding first output signal.
