中文摘要: 针对射电天文毫米波超外差混频接收机本振信号源设计需求,项目拟研究小型化、高频率稳定度半导体本振信号源。首先阐述了项目研究的重要意义,然后比较了几种常用半导体毫米波倍频方案,对比目前几种主要半导体材料的特点,最终选定硅基CMOS工艺,结合采用毫米波注入锁定锁相环倍频方案设计实现。该方案相比先前肖特基二极管倍频方案,可以获得更低输出频率相位噪声,同时提高输出信号功率;相比于超导分频方案,可以降低环境温度要求、减小体积与功耗。项目将在研究硅基65nmCMOS工艺、完成毫米波电磁建模与评估电磁参数对CMOS仿真与版图设计影响基础上,重点设计试制毫米波注入锁定锁相环倍频信号源。

英文摘要: A high stability of semiconductor miniaturization local oscillator is studied to meet the need of millimeter-wave superheterodyne mixing receiver in radio astronomy. Firstly, we expound the important significance of the project, then compare some different scheme on millimeter-wave semiconductor frequency multiplier and different features of the commonest semiconductor material, at last, we will design a local oscillator with injection locking PLL frequency synthesizer scheme based on silicon CMOS technology. The PLL-based scheme would gain the lower phase noise and the better frequency stability compared with the previous scheme of Schottky diode frequency multiplication. The PLL-based signal source would also largely reduce requirement of environment temperature , decrease volume and power dissipation. Firstly in this project, we would research device modeling and parameter extraction of millimeter-wave band in silicon-based 65nm CMOS process, and secondly the EM parameter effect to circuit simulation and layout design would be discussed, above all, the novel key technology of injection locking PLL architecture on millimeter wave band would be studied.
