Abstract
Embodiments of a digital-to-time converter (DTC) and methods for generating phase-modulated signals are generally described herein. In some embodiments, a divide by 2N+/−1 operation on an oscillator signal generates first and second divider signals, the first divider signal is sampled to provide a rising-edge correlated signal, a divider unit output signal is sampled to provide a falling edge correlated signal, and either the second divider signal or a delayed version of the second divider signal is provided as the divider unit output signal. A selection between the rising-edge and the falling-edge correlated signals generates edge signals. A fine phase-modulated output signal is generated based on an edge interpolation between a first and second edge signals.
