An 8‐bit digital‐to‐time converter with pre‐skewing and time interpolation
IET Circuits, Devices and Systems, 2021 This study presents an 8‐bit delay line digital‐to‐time converter (DTC) with pre‐skewing and digital time interpolation. Pre‐skewing that lowers the per‐stage‐delay of delay lines beyond that set by the chosen technology is investigated.
