双图改进节点法及其应用

与其它方法相比，通过用双图法建立电路网络方程组，可以大大地降低方程组的阶数，显著减少非零元。在处理含有较多受控电压源和受控电流源或短路的电路，其效果较为明显，尤其是处理开关电容电路。并且，双图法还适用于一些特殊的非线性电路。     

A 14.5Gb/s word alignment circuit in 0.18μm CMOS technology for high-speed SerDes

This paper presents a word alignment circuit for high speed SerDes system.By using pipeline structure and circuit optimization techniques,the speed of the aligner is increased,and its performance is improved further through adopting the full custom design method.The proposed word aligner has fabricated in 0.18μm CMOS technology with total area of 1.075 ×0.775mm~2￣ including I/O pad.Measurement results show that this circuit achieves the maximum data rate of 14.5Gb/s,while consuming a total power of 34.9mW from a 1.8V supply.
