Abstract
A circuit according to an example includes a digital-to-time converter configured to receive an oscillator signal and to generate a processed oscillator signal based on the received oscillator signal in response to a control signal, and a time-interleaved control circuit configured to generate the control signal based on a time-interleaved technique.
Claims21
A circuit comprising:
- a digital-to-time converter configured to receive an oscillator signal and to generate a processed oscillator signal based on the received oscillator signal in response to a control signal;
- and
- a time-interleaved control circuit configured to generate the control signal based on a time-interleaved technique,
- wherein the control circuit is configured to receive a frequency offset signal and to generate a plurality of polyphase signals, each polyphase signal corresponding to a phase shift with respect to the processed oscillator signal, wherein the control circuit is further configured to generate the control signal by combining the polyphase signals in the proper phase.
