中文摘要:
      提出一种全MOS器件补偿温度和沟 调效应电流控制环形振荡器,以减小通信时钟恢复电路振荡器的振荡频率偏移. 与传统振荡器相比,该振荡器采用全MOS器件设计温度和偏置电流补偿电路,在增强可靠性的情况下降低了温度和沟调效应引起的频率偏移. 电路采用0.35μm标准MOS工艺设计,通过与传统振荡器性能进行仿真比较,该方法振荡频率的偏移量得到明显改善.
英文摘要:
      A temperature and channeling effect-minimized current controlled ring oscillator (CCO) using all MOS devices is presented,for the improved frequency offset of the oscillator in the communication system’s clock recovery circuit. Compared with the conventional oscillator,the oscillator is characterized by the all MOS devices designed temperature and bias current compensation circuits,so as to strengthen the oscillator ’s reliance and alleviate the frequency offset caused by the temperature and channeling effect,respectively. Simulated with a 0.35μm standard MOS process and compared with that of the conventional one,the results shows that the frequency offset performance of the oscillator has been significantly improved.
