Cet article présente un récepteur WLAN compatible avec le signal OFDM 1024-QAM en technologie CMOS 65 nm. Une correction de désadaptation IQ indépendante de la fréquence basée sur le bruit thermique et une correction de désadaptation IQ dépendant de la fréquence avec bouclage de bande de base sont proposées pour l'auto-étalonnage dans le récepteur. Le taux de rejet d'image mesuré de l'auto-étalonnage est de -56.3 dB. Le récepteur atteint l'EVM extrêmement faible de -37.1 dB même avec une large bande passante de canal de 80 MHz et a la capacité de recevoir le signal 1024-QAM. Le résultat indique que le récepteur est extensible pour le récepteur compatible 802.11ax qui prend en charge un schéma de modulation de densité plus élevée de MIMO.

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.
