ルタを形成させてなる電圧制御発振器。[Claims for Utility Model Registration] An unstable multiplier in which the collectors of a pair of transistors are connected to each other's bases and are also connected to a pair of resistors, and a capacitor is connected between the emitters of the pair of transistors. In a voltage controlled oscillator in which the operating current of the vibrator is changed by a control voltage to control the oscillation frequency, the pair of resistors is formed with a polycrystalline silicon layer to have a relatively low resistance value, and the pair of resistors is formed to have a relatively low resistance value. A voltage controlled oscillator that is formed by connecting a microcapacitor to each end of a resistor to form a low-pass filter with a predetermined cut-off frequency.
