Abstract
A voltage-controlled oscillator (VCO) includes an inductor-capacitor (LC) tank circuit, tuning circuitry, and a plurality of first varactors. The LC tank circuit is configured to produce an oscillating signal and is operable in a plurality of frequency bands. The tuning circuitry is configured to tune the LC tank circuit to operate in a first frequency band of the plurality of frequency bands based at least in part on a temperature of the VCO. The plurality of first varactors are coupled to the LC tank circuit for tuning the oscillating signal to a target frequency within the first frequency band based on a control voltage.
