Method and apparatus for noise compensation in an oscillator circuit |
摘要 |
A variable capacitance circuit includes a first and a second capacitor. A switch having an associated first nonlinear capacitance, selectively couples the first and second capacitors. To compensate for the first nonlinear capacitance, a second nonlinear capacitance is coupled to the switch that has a capacitance value responsive to a change in voltage that moves in a direction of change opposite to a direction of change of the first nonlinear capacitance.
