摘要
本文采用0.18μmCMOS工艺设计了用于2.5Gb/s收发器系统的16:1复用器电路。该电路采用数模混合的方法进行设计,第一级用数字电路实现16:4的复用,第二级用模拟电路实现4:1的复用,从而实现16:1的复用器。该电路采用SMIC0.18μm工艺模型,使用Virtuoso AMS Simulator工具进行了仿真。仿真结果表明,当电源电压为1.8V,温度范围为0～70℃时,电路可以工作在2.5b/s,功耗约为6mW。
A 16:1 multiplexer for 2.5Gb/s transceiver system designed with 0.18μm CMOS technology is presented in this paper. The circuit is designed with digital/analog mixed-signal methodology. The first level is realized with digital circuit for the 16:4 multiplex-er , and the second level realize the 4:1 multiplexer by analog circuit. The circuit is simulated with SMIC 0.18μm CMOS model by Virtuoso AMS Simulator. It is shown that the circuit can run at a high speed of 2.5Gb/s under a 1.8V power supply and the temp...
