Several 3 - bit variable optical fiber delay units are designed and analysed on the basis of the conditions of our laboratory 依据实验室现有的一些条件,列出了几种能够实现的3 - bit可变光纤延迟单元的结构,并做了相应分析。
On one hand , the structure of delay unit is redesigned . in the case of the structure composed of three 2 2 optical switches , the relations between the status of optical switches and delay error are analysed by calculation and deduction , then a new delay unit composed of six 1 2 optical switches is designed and take place of the tranditional structure 一方面,改进可变光纤延迟单元的结构,以3个2 2光开关构成的延迟单元为例,对其开关状态与延时误差之间的关系进行了理论分析和公式推导,并根据这一结果设计了由6个1 2光开关构成的具有较低延时误差的3 - bit可变光纤延迟单元。
The main contribution of the thesis is seen as follows : aiming at the fault with slow speed and high power dissipation of the conventional phase - frequency detector , a high speed and low power dissipation phase - frequency detector is designed by modifying the structure of the single phase lock dynamic d flip - flop and adding the delay cell in the feedback loop to eliminate the phase detector ’ s dead zone effectively 论文的主要贡献为以下几个方面: 1 .针对传统鉴频鉴相器速度慢、功耗高的缺点,改进了单相时钟动态d触发器的结构,设计出了一种高速低功耗的鉴频鉴相器,在反馈回路上加入延迟单元,能有效的消除鉴相死区。
