项目摘要

(1) A designed method of a millimeter-wave CMOS radiation oscillator has been developed for broadband short-range communication. An above-chip patch antenna was proposed for the radiation oscillator. The proposed antenna has a balanced port, which makes it suitable for the direct connection of CMOS cross-coupling transistors. The properties of the antenna were analyzed by an electromagnetic field solver, and, in particular, the input resistance was discussed in detail, so that the condition of millimeter-wave oscillator is satisfied even by CMOS FETs having gains lower than GaAs FETs. Furthermore, on/off-keying modulation can be carried out using switch transistors, and two switching techniques are used to realize a large data rate. A performance of 500Mb/s and a total efficiency of 0.12, which includes both the antenna and the circuit efficiencies, were confirmed by circuit simulation.(2) A500-Mb/s12-mW pulsed UWB transceiver has been developed in 1.8-μm CMOS technology for sub-meter short-range wireless communication. The transceiver employs two functional blocks for reducing power dissipation: one is an on-chip transformer-based DC-RF pulse power converter and another is an asynchronous RF baseband direct demodulator. The prototype chip with printed dipole antenna can operate at a bit-error rate of 0.001 or less on 40-cm distance, while dissipating less than 24μW/Mb/s.

(1)提出了一种用于宽带短距离通信的毫米波CMOS辐射源的设计方法。提出了一种用于辐射振荡器的片上贴片天线。所提出的天线具有平衡端口，这使得它适合于CMOS交叉耦合晶体管的直接连接。通过电磁场求解器分析了天线的特性，特别是详细讨论了输入电阻，使得即使CMOS FET的增益低于GaAs FET，也满足毫米波振荡器的条件。此外，可以使用开关晶体管来执行开/关键控调制，并且使用两种开关技术来实现大的数据速率。电路仿真结果表明，该天线的性能为500 Mb/s，总效率为0.12，包括天线效率和电路效率。(2)采用1.8 μ mCMOS工艺，研制了一款500 Mb/s12 mW脉冲超宽带收发器，用于亚米级短距离无线通信。该收发器采用两个功能块来降低功耗：一个是基于片上变压器的DC-RF脉冲功率转换器，另一个是异步RF基带直接解调器。采用印刷偶极子天线的原型芯片在40 cm距离上的误码率小于0.001，功耗小于24μW/Mb/s。
