본 논문에서는 1024nm CMOS 기술의 65-QAM OFDM 신호 지원 WLAN 수신기를 제시합니다. 수신기의 자체 교정을 위해 열 잡음 기반 IQ 주파수 독립적 불일치 보정과 기저대역 루프백을 사용한 IQ 주파수 종속 불일치 보정이 제안되었습니다. 측정된 자체 보정의 이미지 거부율은 -56.3dB입니다. 수신기는 37.1MHz의 넓은 채널 대역폭에서도 -80dB의 매우 낮은 EVM을 달성하고 1024-QAM 신호를 수신할 수 있는 기능을 갖추고 있습니다. 결과는 MIMO의 더 높은 밀도 변조 방식을 지원하는 802.11ax 호환 수신기에 대해 수신기를 확장할 수 있음을 나타냅니다.

Abstract: This paper presents a 1024-QAM OFDM signal capable WLAN receiver in 65nm CMOS technology. Thermal noise-based IQ frequency-independent mismatch correction and IQ frequency-dependent mismatch correction with baseband loopback are proposed for the self-calibration in the receiver. The measured image rejection ratio of the self-calibration is -56.3dB. The receiver achieves the extremely low EVM of -37.1dB even with wide channel bandwidth of 80MHz and has the ability to receive the 1024-QAM signal. The result indicates that the receiver is extendable for the 802.11ax compliant receiver that supports a higher density modulation scheme of MIMO.
