A Ka‐band tunable LNA for MB‐OFDM application

IET Communications, 2021
In this paper a novel tuneable LNA is presented. This LNA is designed with two separated structures which both of them utilize noise cancellation technique and some other approaches such as gain boosting and T‐transformer feedback.

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.
