Dear editor,In the development of 5G prototype systems and terminal demonstration platforms, a wireless channel emulator plays a crucial role in the test and verification process.With online and real-time simulation characteristics such as path loss, shadowing and multi-path fading of transmitted signals from antenna ports in a wireless environment, a wireless channel emulator can accurately measure the effects of wireless environments on system performance.

An e-band high speed power detector MMIC using 0.1 μm pHeMT technology has been designed, manufactured and experimentally characterized. By employing a 4-way quadrature structure for phase cancellation, the first, second and third harmonics can be suppressed and the ripple at the output is minimized. Compared to conventional topology with a low pass filter, a short response time and high speed performance of demodulation can be reached. Simulated results indicate that the detector is capable of demodulating an on-off keying signal at a data rate up to 5 Gbps. The fabricated chip occupies 1× 1.5 mm2 and the on-wafer measurement shows a return loss of less than -15 dB, responsivity better than 700 mV/mW and dynamic range of more than 25 dB over 70 to 90 GHz.

Due to the very high demand for Internet data capacity from mobile and fixed customers as well as the saturation of conventional frequency bands by numerous services, many countries have opened the e band, for broadcasting services. e-band involves the creation of a significant number of links in a given area. The present work addressed the problem that arises in the context of transmission is that of assigning the frequencies of this band to these multiple transmission links. The aim of this work is to study and plan the radio links of the 80 GHz frequency and to implement them in a tool in order to define an optimal distribution on the telecommunications network by guaranteeing maximum flow of data traffic while minimizing the interference. The contribution of this work is part of its unique subject: the planning of e-band frequencies for improving the quality of service of transmission in the network of telecommunications operators. Also, it intends to contribute to the resolution of unsatisfied situations of poor planning of e-band radio frequencies in telecommunications networks. With the aim of opening several opportunities for alternative high-speed data transport solutions, our work has helped prove that e-band transmission links are very efficient with capacities in the gigabyte range.

Test results for a 10-Gbps prototype demonstrator working at 71~76 GHz frequency band with a 2-bit/s/Hz spectral efficiency are reported.To overcome the speed limitation of the commercial DA/ADs,a two-channel analog IF multiplexing and demultiplexing topology is adopted as a trade-off between cost and spectrum efficiency.The same approach is also used to achieve up to 20 Gbps with a full 10-GHz bandwidth of the allocated commercial bands(71~76 GHz and 81~86 GHz).

e-band无线通信频段信道带宽大、传输速率快、安全性高,有利于数公里的点对点高速数据传输。硅基CMOS集成电路集成度高、成本低,并且随着工艺的进步截止频率不断提升,逐渐成为毫米波集成电路的常用工艺之一。本文基于65nm CMOS工艺,设计了两款能够满足e-band低频段(71-76GHz)和高频段(81-86GHz) eTSI、FCC通信协议的频率综合器,取得的成果如下：1、根据e-band无线通信协议的指标要求,采用Matlab Simulink对锁相环路进行建模,确定了频率综合器的系统指标和环路滤波器参数。2、为了在硅基工艺上实现准确的无源器件,电感和变压器通过ADSMomentum工具进行电磁场参数提取,将得到的电磁场参数代入到电路中,进行“场”“路”协同仿真,保证仿真结果的准确性。3、针对e-band低频段和高频段,设计了基频输出的VCO。由于工艺库的电感只提供40GHz以下精确模型,谐振腔电感采用自建U形传输线电感,在.80GHz其Q值为26。优化了可变电容的尺寸以在品质因数和调谐范围之间作更优折衷,在80GHz可变电容的Q值为24.3。毫米波VCO振荡频率对交叉耦合管的寄生电容较为敏感,在电流密度和finger长度这两方面对交叉耦合管尺寸进行优化以提高其fT,缓解了调谐范围和起振条件间的折衷。缓冲器采用共源共栅结构提升增益和隔离度,级间信号通过变压器耦合。设计了四款用于单独测试的VCO,输出频率依次为71-76GHz、76-81GHz、81-86GH、86-91GHz,以更直接评估71-91GHz频段硅基CMOS VCO'性能。根据后仿真结果,e-band 71-76GHz VCO的调谐范围为70.97-76.76GHz, VCO谐振腔功耗为10.8mW,在1MHz和10MHz频偏处相位噪声分别为-89.47dBc/Hz和-116.2dBc/Hz: e-band 81-86GHz VCO的调谐范围为80.84-86.82GHz, VCO谐振腔功耗为9.74mW,在1MHz和10MHz频偏处相位噪声分别为-87.22dBc/Hz和-114.3dBc/Hz。4、设计了由ILFD、动态CML四分频器和7级静态CML二分频器级联形成的分频链路,总分频比为1024。ILFD采用差分注入提升注入效率,加入了两位控制字进行离散调谐以扩展分频范围,后仿真得到分频范围分别为70-77.5GHz和80-88GHz;动态CML四分频器通过调节偏置电压可改变分频器的自激振荡频率,进一步扩展分频范围,后仿真表明偏置电压在0.05-0.5V变化时,分频器的分频范围达到22-56GHz。5、基于65nmCMOS工艺,设计了两款整数分频锁相环频率综合器。根据后仿真结果,71-76GHz和81-86GHz的PLL整体功耗分别为244mW和234.3mW,输出频率范围分别为70.97-76.76GHz和80.84-86.82GHz,1MHz频偏处相位噪声分别为-85.8dBc/Hz和-84.9dBc/Hz,10MHz频偏处相位噪声分别为-111.2dBc/Hz和-110.2dBc/Hz,参考杂散分别为-46dBc和-47.1dBc,环路带宽均为900kHz,锁定时间均为8.8μS。本论文研究受上海市科委“科技创新行动计划”《e-band超高速无线通信毫米波信号源芯片技术研究》(13511500702)资助。

A layout and connection optimization for static frequency divider is presented. The layout optimization provides a new circle topology transistors placement and reasonable connection structure, which reduces the parasitic effectively and enables self-oscillation frequency enhancement. Besides, bandwidth enhancement techniques based on a center-tap capacitor in input balun design and inductive peaking in latch design are adopted to improve further high frequency performance with low power consumption. As a proof of concept, design of a divide-by-2 static frequency divider in 0.13 μm SiGe BiCMOS technology is reported. With single-ended input clock signal, the divider is measured to be operated from 40 to 90 GHz. Phase noise measurements of a 90 GHz input clock signal indicate ideal behavior with no measurable noise contribution from the divider. The divider followed by a buffer that can deliver more than-10 dBm output power, which is sufficient to drive succeeding stage. To the author's knowledge, the divider exhibits a competitive power dissipation and the highest FOM among silicon based frequency dividers that operating higher than 70 GHz.
