A current controlled oscillator is provided for reducing oscillation frequency variation because of temperature dependence of the current amplification efficiency of transistors, comprising a differential amplifier having a pair of transistors, a capacitor collected between collectors of the pair of transistors, and a positive feedback circuit for turning each of the pair of transistors to ON and OFF alternately and complementarily. A temperature compensation circuit is provided for supplying one of the collectors of the pair of transistors with a compensation current proportional to a base current of one of the pair of transistors at status ON together with a constant current.
