  • Publication number: 20220239254
    Abstract: Temperature compensated oscillators and associated methods are disclosed. The oscillator may include an inverter with a variable load configured to provide different conductance values based on an operating temperature of the oscillator. The variable load includes two or more branches in parallel, where each branch has a unique conductance value different from each other. Further, the variable load is coupled to a temperature sensor that generates signals based on determining the operating temperature. The signals of the temperature sensor can activate one or more branches of the variable load. As a result, the inverter may trigger at different voltage levels such that variations in the frequency of the clock signal that the oscillator generates can be reduced across different operating temperatures.
