Abstract
An integrated circuit is provided. The integrated circuit comprises a voltage controlled oscillator and a first compensation capacitor. The voltage controlled oscillator generates an oscillation signal. The first compensation capacitor, coupled in parallel to the voltage controlled oscillator, receives a control voltage to generate a negative temperature coefficient capacitance to compensate for frequency drift of the oscillation signal. The control voltage is temperature dependent.
