ABSTRACT:
Some of the embodiments of the present disclosure provide an apparatus comprising a voltage controlled oscillator (VCO) having a first transistor, a first resistor operatively coupled between a first terminal of the first transistor and a first node, a first capacitor operatively coupled between a second terminal of the first transistor and the first node, and a second capacitor operatively coupled to the first node, wherein the first capacitor and the second capacitor forms a capacitive voltage divider. Other embodiments are also described and claimed.
