摘要
基于超宽带射频(RF)收发电路的应用,设计了一种正交输出的超宽带、全集成并且可重构的频率综合器,可适用于25 MHz~12 GHz工作频段的射频接收、发射电路中射频信号的上变频和下变频处理。采用电荷泵频率综合器作为整体实现架构,使用双核压控振荡器(VCO)覆盖频率范围,利用多级级联本振信号生成技术产生本振信号,实现了适用于多频段一体化通信、雷达无线电跳频、软件定义无线电的频率综合器。采用CMOS工艺进行了设计仿真和流片,芯片尺寸为0.658 mm×1.2 mm。测试结果表明,12 GHz相位噪声不大于-85 dBc/Hz@100 kHz offset,电路典型总功耗为203 mW。
Based on the application of ultra-wide band radio frequency(RF)transceiver circuit,an ultra-wide band,fully integrated and reconfigurable frequency synthesizer with orthogonal output is designed,which is suitable for the up-conversion and down-conversion processing of RF signals in the RF transmition and RF transceiver in the working frequency ranged from 25 MHz to 12 GHz.Using a charge pump frequency synthesizer as the overall implementation architecture,a dual-core voltage controlled oscillator(VCO)to cover the frequency range,and a multistage cascade local oscillator signal generation technology to generate local oscillator signal,a frequency synthesizer applied to multi band integrated communication,radar RF hopping and software-defined radio is realized.The CMOS process is used for design simulation and tape-out,and the final die size is 0.658 mm×1.2 mm.Test results show that the phase noise at 12 GHz is less than-85 dBc/Hz@100 kHz offset,and the typical total power consumption of the circuit is 203 mW.
