Abstract
An oscillation circuit includes an oscillator and a buffer coupled to the oscillator. The oscillator is used to provide at least one oscillation signal according to an analog control signal. The buffer includes at least one input terminal, at least one output terminal, a buffer unit, a first capacitor array and a second capacitor array. The at least one input terminal is used to receive the at least one oscillation signal. The at least one output terminal is used to provide at least one buffered signal. The buffer unit is coupled between the at least one input terminal and the at least one output terminal. The first capacitor array is used to change a first equivalent capacitance value according to at least one first digital signal. The second capacitor array is used to change a second equivalent capacitance value according to at least one second digital signal.
