Inductor-capacitor (lc)-voltage controlled oscillator (vco) and method of operating the same

A method of operating an inductor-capacitor (LC)-voltage controlled oscillator (VCO), comprising:

• generating, using a current generation circuit of the LC-VCO, a proportional to absolute temperature (PTAT) current;
• generating, using a varactor bias voltage generation circuit of the LC-VCO, a varactor bias voltage based on the PTAT current and on both a process condition and a temperature condition that are associated with the LC-VCO;
• and
• adjusting, using a LC tank of the LC-VCO, an effective gate overdrive voltage of a capacitor of the LC tank based on the varactor bias voltage to compensate for a process variation of the process condition and a temperature variation of the temperature condition.
