Abstract:
A method and a circuit for increasing a resolution of a digitally controlled oscillator include controlling the oscillator so that an output signal of the oscillator varies between semi-periods having a first frequency and semi-periods having a second frequency. The method and circuit further include applying the output signal of the oscillator as an input to a divider to obtain a divided signal. A frequency of at least one semi-period of the divided signal is a function of both an oscillator semi-period having the first frequency and an oscillator semi-period having the second frequency.
