2017年10月发布的IEEE标准802.15.3d定义了一个高数据速率的无线物理层，该物理层使用252到325 GHz之间的较低太赫兹频率范围(以下称为“300 GHz频段”)实现高达100 Gb/S。它规定300 GHz频段被信道化成32个2.16 GHz宽的信道(图9.5.1)，或者更少数量的带宽都是2.16 GHz的整数倍的更宽的信道。本文介绍了一种针对802.15.3d(图9.5.1)通道49至51和66的芯片。TRX采用40 nm CMOS工艺制作而成。已经有关于工作在300 GHz频段或接近300 GHz频段的固态收发机(TRX)的报道[1]-[6]。其中一些[1]-[3]是TX/RX或块级芯片组，可以在设计上享有更大的灵活性，并对TX和RX进行独立优化。他们成功地实现了$Gb/S。另一方面，单片TRX[4]-[6]并不总是显示可实现的数据速率，也不能支持正交幅度调制(QAM)。然而，最终开发全功能的单芯片TRX是可取的，特别是对于需要部署许多TRX的应用，正如802.15.3d隐含地设想的那样。本文提出的支持QAM的单芯片CMOSTRX就是朝着这个方向努力的结果。
IEEE Standard 802.15.3d, published in October 2017, defines a high-data-rate wireless physical layer that enables up to 100Gb/s using the lower THz frequency range between 252 and 325GHz (hereafter referred to as the “300GHz band”). It stipulates that the 300GHz band be channelized into thirty-two 2.16GHz-wide channels (Fig. 9.5.1) or a smaller number of wider channels whose bandwidths are all integer multiples of 2.16GHz. This paper presents a CMOS transceiver (TRX) chip targeted at channels 49 through 51 and 66 of 802.15.3d (Fig. 9.5.1). The TRX was fabricated using a 40nm CMOS process. There have been reports on solid-state transceivers (TRXs) operating in or near the 300GHz band [1]–[6]. Some of these [1]–[3] were TX/RX or block-level chipsets, which can enjoy more flexibility in design and independent optimization of TX and RX. They successfully achieved $\geq 64$ Gb/s. On the other hand, single-chip TRXs [4]–[6] did not always reveal achievable data-rates nor were capable of supporting quadrature amplitude modulation (QAM). Nevertheless, eventual development of full-featured single-chip TRXs is desirable especially for applications requiring deployment of many TRXs, as is envisioned implicitly by 802.15.3d. The single-chip QAM-capable CMOS TRX presented herein is an outcome of efforts in that direction.
