It is realized in 22 nm FD-SOI CMOS and exploits the use of back-gate biasing. The new approach features strong tolerance to process, voltage and temperature (PVT) variations and thus can maintain low phase error with fine phase tuning capability supporting a large bandwidth. Measurement results show that the 4-bit phase shifter achieves 3.5° rms phase error at 28 GHz. The proposed phase shifter can maintain <5° of the worst-case rms phase error when operating across 24 to 29.5 GHz resulting in 20.56% fractional bandwidth which is the largest among the published switched-filter phase shifters to date.||Funding Details:||Science Foundation Ireland||Type of material:||Conference Publication||Publisher:||IEEE||Copyright (published version):||2021 IEEE||Keywords:||Temperature measurement; Phase measurement; Transmitters; Phase shifters; Measurement uncertainty; Switches; Topology||DOI:||10.1109/ESSCIRC53450.2021.9567845||Other versions:||https://www.esscirc-essderc2021.org/||Language:||en||Status of Item:||Peer reviewed||Is part of:||ESSCIRC 2021 - IEEE 47th European Solid State Circuits Conference, Proceedings||Conference Details:||The IEEE 47th European Solid State Circuits Conference (ESSCIRC 2021), Virtual Conference, 6-9 September 2021||ISBN:||9781665437479||This item is made available under a Creative Commons License:||https://creativecommons.org/licenses/by-nc-nd/3.0/ie/|
