Abstract: Aspects of the present disclosure include systems and methods for temperature adaptive voltage controlled oscillators. In one example, a voltage controlled oscillator includes a cross junction circuit electrically coupled to a temperature dependent input current, and an inductor circuit electrically coupled to the cross junction circuit. The voltage controlled oscillator additionally includes a capacitor bank circuit electrically coupled to the inductor circuit, and an input node that receives a control voltage. The voltage controlled oscillator further includes an output node configured to provide an oscillation frequency output, wherein the oscillation frequency output is controlled by the control voltage.
