Abstract: Provided is an LC resonance voltage-controlled oscillator (VCO) used for a multi-band multi-mode wireless transceiver. In order to generate a multi-band frequency, a capacitor bank and a switchable inductor are included in the LC resonance voltage-controlled oscillator. The LC resonance voltage-controlled oscillator employs an adjustable emitter-degeneration negative resistance cell in place of tail current sources in order to compensate for non-uniform oscillation amplitude caused by the capacitor bank and prevent the degradation of a phase noise due to the tail current sources. The LC resonance voltage-controlled oscillator includes an inductor providing an inductance element partially determining the frequency of an oscillation wave; a discrete capacitor bank providing a capacitance element partially determining the frequency of the oscillation wave and being discretely determined by a control bit signal; and a discrete negative resistance cell providing a negative resistance element that is discretely determined by the control bit signal, to keep the amplitude of the oscillation wave constant.
