设计了一种工作在2.4 GHz的CMOS高电压整流器。采用四级NMOS二极管连接的电荷泵结构,从器件选型、尺寸、负载阻抗等方面,对整流器进行优化设计,提高了输出电压与功率转换效率。另外,在实际设计中考虑了封装管脚的寄生效应,消除了封装对匹配的影响。该整流器在CSMC 0.153 μm CMOS工艺下进行流片和测试。结果显示,该整流器在2.4 GHz 频段附近S11<-10 dB,匹配良好,功率转换效率的峰值为21.3%,输出电压为4.6 V。 相似文献

正This paper presents a broadband Gilbert low noise mixer implemented with noise cancellation technique operating between 10 MHz and 0.9 GHz.The Gilbert mixer is known for its perfect port isolation and bad noise performance.The noise cancellation technique of LNA can be applied here to have a better NF.The chip is implemented in SMIC 0.18μm CMOS technology.Measurement shows that the proposed low noise mixer has a 13.7-19.5 dB voltage gain from 10 MHz to 0.9 GHz,an average noise figure of 5 dB and a minimum value of 4.3 dB.The core area is 0.6 x 0.45 mm~2. 相似文献
