VARACTOR FOLDING TECHNIQUE FOR PHASE NOISE REDUCTION IN ELECTRONIC OSCILLATORS
摘要
A varactor folding technique reduces noise in controllable electronic oscillators through the use of a series of varactors having relatively small capacitance. A folding circuit provides control signals to the varactors in a sequential manner to provide a relatively smooth change in the total capacitance of the oscillator. Consequently, effective control of the oscillator is achieved with accompanying reductions in oscillator noise such as flicker noise.
