项目摘要
The B2 project of Meteracom focuses on the signal traceability in electronic THz analog transmit and receive frontends, including their functional building blocks for wideband THz signal generation, translation, amplification and sampling. The main objectives in phase II are to expand the transceiver functionalities towards the traceability of impairments on the physical chip level, to improve the THz frequency synthesizer based on the optoelectronic PLL and to conduct joint THz communication experiments. Building on the THz transceiver chip sets and the comprehensive electro-magnetic circuit design flow established in phase 1, the transceiver MMICs shall be enhanced through self-test, self-calibration and in-circuit test functionality, by including scalar or vectorial power detectors between functional transceiver stages (PI Kallfass). Furthermore, the transceivers shall be equipped with variable gain amplifiers for automatic gain control. The resulting “traceable THz transceivers” will provide a measurement platform for the calibration of the physical transceiver model in project C3, and provide measurement data for the machine-learning oriented projects C1 and C2 and the traceability project T. Right from the start of phase 2, the B2 project will provide measurement data to fellow projects obtained from an existing 300 GHz link capable of frequency-division-multiplexing and complex digital modulation up to 256 QAM inline with the IEEE802.15.3d standard. The wideband THz synthesizer based on an optoelectronic PLL (OEPLL) which was demonstrated in the first phase shall be further improved (PI Scheytt). The improvements target even lower phase noise and improved frequency tuning resolution. The phase noise and spurs of the modified OEPLL will be mathematically analyzed and modelled. An improved OEPLL synthesizer will be built and measured to validate the mathematical analysis. The model of the improved OEPLL synthesizer will be integrated into the physical transceiver model of C3. Regarding optical sampling techniques (PI Schneider, PI Scheytt), in the first phase the major error sources have been determined to be the jitter of the RF source, the phase noise of the CW laser or MLL, respectively, and nonlinearity. In the second phase, we will build on these results and, in strong collaboration with A3, we will use algorithms and models developed in C3 for the evaluation of THz communication experiments.
Meteracom的B2项目专注于电子THz模拟发射和接收前端的信号可追溯性,包括宽带THz信号生成,转换,放大和采样的功能构建模块。第二阶段的主要目标是扩展收发器的功能,实现物理芯片级损伤的可追溯性,改进基于光电PLL的太赫兹频率合成器,并进行联合太赫兹通信实验。在THz收发器芯片组和第1阶段建立的综合电磁电路设计流程的基础上,通过在功能收发器级之间包括标量或矢量功率检测器(PI Kallfass),将通过自测试、自校准和在线测试功能增强收发器MMIC。此外,收发器应配备可变增益放大器,用于自动增益控制。由此产生的“可追溯THz收发器”将为项目C3中的物理收发器模型的校准提供测量平台,并为面向机器学习的项目C1和C2以及可追溯性项目T提供测量数据。从第二阶段开始,B2项目将为其他项目提供测量数据,这些数据是从现有的300 GHz链路中获得的,该链路能够进行频分复用和复杂数字调制,最高可达256 QAM,符合IEEE 802.15.3d标准。在第一阶段演示的基于光电PLL(OEPLL)的宽带THz合成器将进一步改进(PI Scheytt)。改进的目标是更低的相位噪声和改进的频率调谐分辨率。对改进后的OEPLL的相位噪声和杂散进行了数学分析和建模。为了验证数学分析的正确性,我们将建立一个改进的OEPLL频率合成器并进行测试。改进的OEPLL频率合成器模型将被集成到C3的物理收发器模型中。关于光学采样技术(PI Schneider,PI Scheytt),在第一阶段,主要误差源已被确定为RF源的抖动,CW激光器或MLL的相位噪声,分别和非线性。在第二阶段,我们将在这些结果的基础上,与A3密切合作,我们将使用C3开发的算法和模型来评估THz通信实验。
