A switching network exploiting the principle that the resultant phase noise of VCO will be reduced in proportion to 1/ N , if N oscillators are ideally coupled together. The VCO consists of two cross-coupled oscillators joining by a pair of mode-switched inductors. Two pairs of MOS transistors are used to switch high- and low-frequency bands. With even mode (low-band), the voltages across the resonators are in phase with equal amplitude and with odd mode (high-band), the voltages are 180 ^{\circ} out of phase with equal amplitude. When the tank's inductance reduces due to the switching to operate the circuit at the high-frequency band, the capacitance is the same as that at the low-band
