Abstract: Circuitry for controlling the oscillation frequency of an oscillator by using a digitally tunable on-chip capacitor bank. The capacitor bank includes a plurality of on-chip capacitors, each of which is independently selectable by a control signal for providing a selectable amount of capacitance to the oscillator to control the oscillator's oscillation frequency.
