High frequency time interleaved digital to time converter (DTC)

摘要

Described herein are technologies related to an implementation of a time interleaved digital-to-time converter (DTC) topology to generate high frequency phase modulated local oscillator (LO) signals. A first and second DTC are connected to an oscillator where outputs of the two DTCs are combined to generate a phase modulated signal and the two DTCs have a frequency rate that is half the frequency rate of the phase modulated signal. The two DTCs can operate at a 50 percent or lower duty cycle.

1. A device comprising:
a digitally controlled oscillator; first and second digital-to-time converters (DTC) connected together in parallel, wherein the first and second DTCs are coupled to the digitally controlled oscillator; and a logic controller gate configured to combine outputs of the first and second DTCs to generate a phase modulated signal, wherein the first DTC or the second DTC comprises a frequency rate that is half the frequency rate of the phase modulated signal.
