  • Patent number: 12155387
    Abstract: A low power oscillator circuit with temperature compensation is illustrated. A current supply unit of an oscillator used to output an output current which is proportional to a reference current. As the temperature is increased, both a first threshold and the reference current of a unidirectional conduct in the temperature compensation circuit are decreased. Because a delay time of the oscillating signal is proportional to the first threshold voltage, and the delay time is inversely proportional to the reference current, the effects of the first threshold voltage and the reference current on the delay time are canceled, and the delay time of the oscillating signal is not affected by the temperature.
