Abstract
Pulse generation circuitry includes edge generation circuitry and edge combination circuitry. The edge generation circuitry includes a first digital-to-time converter (DTC) configured to input a first phase signal that includes a first phase edge and a second phase signal that includes a second phase edge. The edge generation circuitry is configured to generate a first pulse edge signal comprising a first pulse edge at a selected location between the first phase edge and the second phase edge. The edge combination circuitry is configured to combine the first pulse edge signal and a second pulse edge signal including a second pulse edge to generate a pulse signal.
