摘要

近年来，60GHz载波和9GHz带宽使得超高速无线通信成为可能[1-4]。为了满足快速增长的数据流量需求，IEEE802.11ay标准是最有希望实现100Gb/s数据速率的候选标准之一。在IEEE802.11ay标准中，高阶数字调制(如128QAM)和60GHz的信道绑定都被认为是使用的。然而，必须满足LO馈通(LOFT)和图像抑制比(IMRR)的更严格要求，因此需要在整个9GHz频谱内的内置校准电路中实现更高的精度，用于LOFT和I/Q不平衡校准，以实现所需的EVM。

24.9 A 128-QAM 60GHz CMOS transceiver for IEEE802.11ay with calibration of LO feedthrough and I/Q imbalance

The 60GHz carrier with 9GHz bandwidth enables ultra-high-speed wireless communication in recent years [1–4]. To meet the demand from rapidly-increasing data traffic, the IEEE802.11ay standard is one of the most promising candidates aiming for 100Gb/s data-rate. Both higher-order digital modulation such as 128QAM and channel bonding at 60GHz are considered to be used in the IEEE802.11ay standard. However, the more severe requirements of LO feedthrough (LOFT) and image-rejection ratio (IMRR) have to be satisfied, so much higher accuracy in built-in calibration circuitry is required across the entire 9GHz spectrum for LOFT and I/Q imbalance calibration to achieve the required EVM.
