5G 새로운 무선(NR) 밀리미터파 위상 배열 트랜시버의 어레이 크기가 확대됨에 따라 정확한 빔 제어를 지원하려면 향상된 위상 튜닝 해상도가 필요합니다. 본 논문에서는 능동 벡터 합산 위상 시프터의 CMOS 구현을 소개합니다. 제안된 위상 천이기는 6mm의 활성 영역으로 0.32비트 위상 천이를 구현한다.2. 위상 튜닝 시 이득 변화를 최소화하기 위해 이득 오차 보상 기법이 제안된다. 보상 후 5G NR 대역 n257 내에서 측정된 이득 변화는 0.9dB 미만입니다. 해당 RMS 이득 오류는 0.2dB 미만입니다. 26.5GHz~29.5GHz에서 측정된 RMS 위상 오류는 1.2° 미만입니다. 이 작업을 통해 이득 불변, 고해상도 위상 튜닝이 실현됩니다. EVM(Error Vector Magnitude) 성능을 고려하면 제안된 위상 천이기는 11.2QAM에서 최대 256Gb/s의 데이터 전송률과 25.2mW의 전력 소모를 지원한다.

Abstract: Regarding the enlarged array size for the 5G new radio (NR) millimeter-wave phased-array transceivers, an improved phase tuning resolution will be required to support the accurate beam control. This paper introduces a CMOS implementation of an active vector-summing phase shifter. The proposed phase shifter realizes a 6-bit phase shifting with an active area of 0.32mm2. To minimize the gain variation during the phase tuning, a gain error compensation technique is proposed. After the compensation, the measured gain variation within the 5G NR band n257 is less than 0.9dB. The corresponding RMS gain error is less than 0.2dB. The measured RMS phase error from 26.5GHz to 29.5GHz is less than 1.2°. Gain-invariant, high-resolution phase tuning is realized by this work. Considering the error vector magnitude (EVM) performance, the proposed phase shifter supports a maximum data rate of 11.2Gb/s in 256QAM with a power consumption of 25.2mW.
