Abstract
A tunable DCO (digitally controlled oscillator), for example, includes a clock generator that is arranged to provide a converter clock signal for driving a frequency-to-voltage (F2V) converter. The F2V converter, for example, includes a frequency target control input for selecting an operational frequency and in response generates a frequency control signal using a DAC (digital-to-analog converter). The example F2V converter is arranged using a split capacitor DAC to provide a linear voltage response over a range of trim codes. The clock generator is arranged to generate the converter clock signal in response to the frequency control signal.
