Abstract
Embodiments of the present invention deal generally with circuitry and methods for converting a sampled digital signal ( ) to a naturally sampled digital signal ( ). One embodiment relating to a method includes receiving the sampled digital signal, calculating a duty ratio estimate ( ) using feedback ( ), and using interpolation ( ) to determine the naturally sampled digital signal. Circuitry for converting a sampled digital signal ( ) to a naturally sampled digital signal ( ) includes a natural sampler, where the natural sampler includes an input to receive the sampled digital signal ( ) and an input to receive a feedback signal ( ). The natural sampler has an output to provide the naturally sampled digital signal ( ). In one embodiment, the natural sampler calculates a duty ratio ( ) using the feedback signal ( ) and uses interpolation to determine the naturally sampled digital signal ( ).
