| 摘 要： | 设计了一种应用于多标准收发器的可重构流水线结构模数转换器,通过一个重构配置控制信号动态地配置采样频率的大小及分辨率的位数,以满足不同标准及系统的需要。在设计中还采用了共源共栅两级运放和差分动态比较器来优化电路的速度和功耗。仿真结果表明这种可重构流水线结构模数转换器能够很好地实现采样频率及分辨率位数的可重构。

| Abstract: | A reconfigurable pipelined analog -to -digital converter for a multi -standard transceiver is presented. Its sampling rate and resolution could be reconfigured by a reconfigurable-control-signal to accommodate the requirements of the different stan- dards and systems. The cascode two -stage op -amp and differential dynamic comparator are also used to optimize the speed and power dissipation. The results of simulation show that the reconfigurable pipelined ADC could automatically reconfigure its sampling rat... |
