Claim Text:
1. A frequency oscillator comprising: a tank circuit having an inductor, a first coupling capacitor, and a second coupling capacitor; a varactor circuit electrically coupled to the first coupling capacitor and the second coupling capacitor; a first MOS device having a first gate, a first drain, and a first source, the first source being electrically coupled to the varactor circuit, and the first gate being electrically coupled to the first drain; a second MOS device having a second gate, a second drain, and a second source, the second source being electrically coupled to the varactor circuit opposite the first source and the second gate being electrically coupled to the second drain; a first input electrically coupled to the first drain and the second drain operable to receive a first bias voltage; and a second input electrically coupled to the first gate and the second gate to receive a first gate bias voltage.
