This research presents a wide band pseudo random bit sequence generator (PRBS) that is used for data generation in mm-Wave transmitters, the goal was to design 6 separate loops with accurate time shift to generate the data input needed for the 3 QPSK transmitters combined together for the purpose of generating high order QAM signals from basic QPSK transmitters as in [1] and see Figure 1, the output of PRBS is then distributed and amplified to be sent to 4 array element each of them consists of 3 I/Q transmitters as mentioned for 64 QAM generation, the full circuit schematic for the PRBS loop, the amplification stages, the control unit and the array distribution network are presented, and also the full layout with post extraction results is presented at then end, the chip was fabricated in 45nm GFSOI technology with expected arrival date on July 2023.
