Abstract: An apparatus, including: a switched capacitor configured to generate a switched capacitor voltage based on an input clock signal and a current; a current digital-to-analog converter (DAC) configured to generate the current based on a first digital signal; a first reference voltage generator configured to generate a first reference voltage; and a first voltage comparing device configured to generate a first frequency deviation detection signal based on a comparison of the switched capacitor voltage to the first reference voltage.
