Abstract
A differential Colpitts oscillator circuit is described which provides a larger tuning range, has better phase noise and uses less power than conventional differential Colpitts oscillator circuits. The circuit is characterized by a capacitive ladder in which only variable capacitor is used for tuning the circuit. In some embodiments, a variable capacitor can be used for fine tuning.
