Kertas kerja ini memperkenalkan penukar fasa jenis suis CMOS (STPS) resolusi tinggi dan padat untuk jalur n5 rangkaian mudah alih (5G) generasi ke-260. Dalam kerja ini, empat peringkat peralihan fasa kasar dan peringkat penalaan resolusi tinggi disertakan. Peringkat kasar berdasarkan topologi bridged-T mampu menyediakan liputan fasa 202.5° dengan langkah penalaan 22.5°. Untuk menambah baik lagi resolusi peralihan fasa, peringkat penalaan halus padat meliputi 23° juga disepadukan dengan peringkat kasar. Resolusi peralihan fasa sub-darjah direalisasikan untuk menyokong penentukuran fasa stereng rasuk halus dan ketepatan tinggi dalam radio baharu 5G. Algoritma kawalan fasa yang dipermudah dan kehilangan sisipan yang ditindas juga boleh dikekalkan oleh peringkat penalaan halus yang dicadangkan. Dalam pengukuran, ralat perolehan RMS yang dicapai pada 39 GHz ialah 0.1 dB dan 0.4 dB untuk peringkat kasar dan peringkat halus, masing-masing. Ralat fasa RMS yang dicapai pada 39 GHz ialah 3.1° untuk peringkat kasar dan 0.1° untuk peringkat halus. Dalam 37 GHz hingga 40 GHz, kerugian pulangan yang diukur dalam semua keadaan penalaan fasa sentiasa lebih baik daripada -14 dB. Pengalih fasa yang dicadangkan menggunakan kawasan teras hanya 0.12mm2 dengan proses CMOS 65-nm, yang cekap kawasan.

Abstract: This paper introduces a high-resolution and compact CMOS switch-type phase shifter (STPS) for the 5th generation mobile network (5G) n260 band. In this work, totally four coarse phase shifting stages and a high-resolution tuning stage are included. The coarse stages based on the bridged-T topology is capable of providing 202.5° phase coverage with a 22.5° tuning step. To further improve the phase shifting resolution, a compact fine-tuning stage covering 23° is also integrated with the coarse stages. Sub-degree phase shifting resolution is realized for supporting the fine beam-steering and high-accuracy phase calibration in the 5G new radio. Simplified phase control algorithm and suppressed insertion loss can also be maintained by the proposed fine-tuning stage. In the measurement, the achieved RMS gain errors at 39 GHz are 0.1 dB and 0.4 dB for the coarse stages and fine stage, respectively. The achieved RMS phase errors at 39 GHz are 3.1° for the coarse stages and 0.1° for the fine stage. Within 37 GHz to 40 GHz, the measured return loss within all phase-tuning states is always better than -14 dB. The proposed phase shifter consumes a core area of only 0.12mm2 with 65-nm CMOS process, which is area-efficient.
