|---|---|---|
This paper presents a 1024-QAM OFDM signal capable WLAN receiver in 65 nm 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 -56.3 dB. The receiver achieves the extremely low EVM of -37.1 dB even with wide channel bandwidth of 80 MHz 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. |
