摘　　要：采用0.13μm RF CMOS工艺,设计了一款可应用于EoC收发芯片的三频段上混频器,通过改变接入并联LC负载谐振网络中电容的值,使电路分别工作在1.2GHz,2GHz,2.4GHz频段。在3.3V电源电压下,1.2GHz,2GHz,2.4GHz频段上,总电流为35.1mA;单边带(SSB)电压转换增益分别为3.77dB,4.97dB,4.78dB;输出1dB压缩点分别为-0.22dBm,0.78dBm,0.5dBm;噪声系数分别为5.13dB,5.76dB,6.67dB。通过控制输入跨导级的偏置实现混频器的开启和关断,上混频器的开启时间为200ns,关断时间小于100ns。A novel tri-band up-mixer was designed for EoC transceiver chips based on 0.13 μm RF CMOS process. In the design, the mixer was working at 1.2 GHz, 2 GHz and 2.4 GHz bands under different parallel LC resonant network by changing the output loading capacitance. Under 3.3 V power supply, the up-mixer had a power consumption of 35.1 mA, the SSB voltage conversion gain was 3.77 dB, 4.97 dB and 4.78 dB at each band of 1.2 GHz, 2 GHz and 2.4 GHz, the OP1dB was -0.22 dBm, 0.78 dBm and 0.5 dBm, and the noise figure was 5.13 dB, 5.76 dB and 6.67 dB respectively. The up-mixer could turn on and off by controlling the bias of the input transconductance stage, the total turn-on time was about 200 ns and the turn-off time was less than 100 ns.
