Este artigo apresenta um receptor WLAN com capacidade de sinal OFDM 1024-QAM em tecnologia CMOS de 65nm. A correção de incompatibilidade independente de frequência de QI baseada em ruído térmico e a correção de incompatibilidade dependente de frequência de QI com loopback de banda base são propostas para a autocalibração no receptor. A taxa de rejeição de imagem medida da autocalibração é de -56.3dB. O receptor atinge EVM extremamente baixo de -37.1dB mesmo com ampla largura de banda de canal de 80MHz e tem a capacidade de receber o sinal 1024-QAM. O resultado indica que o receptor é extensível para o receptor compatível com 802.11ax que suporta um esquema de modulação de densidade mais alta 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.
