摘要： There are provided a voltage-controlled oscillator and an RF-IC for W-CDMA, which are capable of ensuring a wide frequency range and improving oscillation stability. The voltage-controlled oscillator (RF-IC) includes: switching A and B inductors generating a magnetic interaction between resonant A and B inductors of a resonant circuit; and an A_NMOS, a B_NMOS, a C_NMOS, and D_NMOS as switch/load means having together a function of changing an inductance value by the magnetic interaction between the resonant A and B inductors and the switching A and B inductors and a function of serving as loads of the switching A and B inductors. The A_NMOS, the B_NMOS, the C_NMOS, and the D_NMOS are turned ON/OFF by a control signal so as to control the mutual induction, whereby the oscillation frequency is switched by changing the inductance value of the resonant circuit. Also, oscillation stability is improved by increasing the inductance value.

摘要： A semiconductor integrated circuit device for communication is provided with a PLL circuit or the like formed therein, the PLL circuit which is capable of realizing the compensation of fluctuation due to temperature change, the inhibition of increase in the chip area and the ensurement of the performance margin, and which controls a VCO having multiple oscillation frequency bands. In the case where automatic calibration is performed by switching a switch to a side of a DC voltage source in the PLL circuit using a VCO having multiple oscillation bands, a tuning voltage (Vtune) of an RFVCO is fixed to a voltage value of a DC voltage source. However, since a temperature characteristic of canceling a VCO oscillation frequency is given to the DC voltage source, it is possible to minimize the influence on the band selection when a calibration table comes to no optimum one.
