### 特征比对表格

技术特征描述及公开性判断结果对比文件原文引用公开性论述
**技术特征A**<br>《直接公开》第0091段:<br>“The transmitter 602 comprises a time base 604 that generates a periodic timing signal 606. The time base 604 typically comprises a voltage controlled oscillator (VCO), or the like, having a high timing accuracy and low jitter, on the order of picoseconds (ps).”<br>(发射机602包括时间基准604,其生成周期性定时信号606。该时间基准604通常包括压控振荡器(VCO)或类似器件,具有高定时精度和低抖动,在皮秒数量级。)对比文件明确公开了发射机包含压控振荡器(VCO),其功能是生成周期性定时信号(即振荡信号)。这与目标专利权利要求中“第一电路,用以产生振荡信号”的技术特征相同。本领域技术人员能毫无疑义地得出对比文件公开了产生振荡信号的电路(VCO)。
**技术特征B**<br>《未公开》无相关描述。对比文件未描述向VCO提供第一电流(静态偏置电流)的“第二电路”。对比文件仅描述了VCO作为时间基准的一部分,未涉及其偏置电路的具体结构或工作方式。因此,该技术特征未被直接或隐含公开。
**技术特征C**<br>《未公开》无相关描述。对比文件未描述任何仅在振荡信号初始期间提供第二电流(增强偏置电流)以加速达到稳态的“第三电路”。该加速启动的概念及相关电路在对比文件中完全没有提及。因此,该技术特征未被直接或隐含公开。
**技术特征D**<br>《未公开》无相关描述。对比文件未描述任何“稳态检测器”,也未提及检测振荡信号频率稳定性(如变化不超过1%)并据此禁止某个电路的功能。因此,该技术特征未被直接或隐含公开。
**技术特征E**<br>《未公开》第0091段:<br>“The voltage control to adjust the VCO center frequency is set at calibration to the desired center frequency used to define the transmitter's nominal pulse repetition rate.”<br>(用于调整VCO中心频率的电压控制在校准时被设定为用于定义发射机标称脉冲重复率的期望中心频率。)对比文件提到了对VCO中心频率的校准设置,但这是在校准时一次性设定以确定脉冲重复率,并非目标专利中所述的“频率校准单元”在运行中持续或定期“调谐所述第一电路,以使得所述振荡信号在频率范围之内循环”的动态过程。两者作用不同,对比文件未公开该技术特征。
**技术特征F**<br>《未公开》无相关描述。对比文件未将提供给振荡电路的电流区分为“静态偏置电流”和“增强偏置电流”。因此,该技术特征未被直接或隐含公开。
**技术特征G**<br>《未公开》无相关描述。对比文件未描述由“静态直流偏置电路”响应于使能信号来控制“第一可控电流源”施加“静态偏置电流”的电路结构。因此,该技术特征未被直接或隐含公开。
**技术特征H**<br>《未公开》无相关描述。对比文件未描述“第一可控电流源”及其连接到振荡电路。因此,该技术特征未被直接或隐含公开。
**技术特征I**<br>《未公开》无相关描述。对比文件未描述由“增强偏置电路”、“可控放大器”和“第二可控电流源”构成的、响应于使能信号产生并施加“增强偏置电流”的电路结构。因此,该技术特征未被直接或隐含公开。
**技术特征J**<br>《未公开》无相关描述。对比文件未描述“频率校准单元”向提供第一电流的电路发送禁用信号,且不向提供第二电流的电路发送禁用信号的操作。因此,该技术特征未被直接或隐含公开。
**技术特征K**<br>《未公开》无相关描述。虽然VCO内部通常包含谐振电路,但对比文件的说明书仅将VCO作为功能模块提及,并未揭示其内部具体构成,例如是否包含“谐振电路”。本领域技术人员无法从对比文件中毫无疑义地或通过合理推断得出VCO必然包含“谐振电路”这一具体特征。因此,该技术特征未被公开。
**技术特征L**<br>《未公开》无相关描述。对比文件未提及“负电阻产生器”或其与谐振电路的耦合。因此,该技术特征未被直接或隐含公开。
**技术特征M**<br>《未公开》无相关描述。对比文件未描述谐振电路的具体组成,包括是否包含“电感器件”。因此,该技术特征未被直接或隐含公开。
**技术特征N**<br>《未公开》无相关描述。对比文件未描述谐振电路中“电容器件”与“电感器件”的并联耦合关系。因此,该技术特征未被直接或隐含公开。
**技术特征O**<br>《未公开》无相关描述。对比文件未提及“可编程开关电容器组”。因此,该技术特征未被直接或隐含公开。
**技术特征P**<br>《未公开》无相关描述。对比文件未将“振荡信号的振幅稳定性”规定为稳态状况的基准。因此,该技术特征未被直接或隐含公开。
**技术特征Q**<br>《未公开》无相关描述。对比文件未规定“振幅变化不超过15%”的稳态条件。因此,该技术特征未被直接或隐含公开。
**技术特征R**<br>《未公开》无相关描述。对比文件未规定“频率范围等于规定的中心频率的1%”。因此,该技术特征未被直接或隐含公开。
**技术特征S**<br>《未公开》无相关描述。对比文件仅提及在校准时设置VCO中心频率,未描述在“装置通电时”、“检测到高于规定阈值的环境温度变化时”或“接收到新的频率字时”动态调谐振荡电路的功能。因此,该技术特征未被直接或隐含公开。
**技术特征T**<br>《直接公开》第0090-0094段、第0103段及图6、图10:<br>对比文件描述了完整的脉冲无线电发射机(图6),其包含VCO(时间基准604)用于产生定时信号,该发射机是通信设备的一部分。图10和说明书描述了移动单元1002包含脉冲无线电发射机1010和接收机1006,用于建立无线通信链路。第0034段指出:“Recent advances in communications technology have enabled an emerging, revolutionary ultra wideband technology (UWB) called impulse radio communications systems”。对比文件公开了包含振荡器(VCO)的收发机(发射机和/或接收机),该振荡器产生的信号用于生成和/或处理脉冲无线电(即超宽带,UWB)信号,从而建立与另一个装置(如脉冲无线电门户)的无线通信信道。这与目标专利中“收发机,所述收发机响应于所述振荡信号而建立与另一个装置的至少一条超宽带通信信道”的技术特征实质相同。
**技术特征U**<br>《直接公开》同上。同特征T的论述。对比文件公开的脉冲无线电系统即用于建立超宽带通信信道。
**技术特征V**<br>《直接公开》同上。同特征T的论述。对比文件公开的脉冲无线电系统即用于建立超宽带通信信道。
**技术特征W**<br>《直接公开》同上。同特征T的论述。对比文件公开的脉冲无线电系统即用于建立超宽带通信信道。
**技术特征X**<br>《直接公开》第0037段:<br>“Impulse radio refers to a radio system based on short, low duty cycle pulses.”<br>第0042段:<br>“In the widest bandwidth embodiment, the resulting waveform approaches one cycle per pulse at the center frequency.”<br>第0068段:<br>“However, far greater processing gains are achieved with impulse radio systems, where for the same 10 KHz information bandwidth is spread across a much greater 2 GHz. channel bandwidth...”<br>(脉冲无线电是指基于短脉冲、低占空比的无线电系统。在最宽的带宽实施例中,所得波形在中心频率处接近每个脉冲一个周期。然而,脉冲无线电系统实现了更大的处理增益,其中相同的10KHz信息带宽分布在更大的2GHz信道带宽上...)对比文件明确其脉冲无线电系统是超宽带(UWB)技术,具有极宽的带宽(例如2 GHz)。虽然未精确重复“20%相对带宽或500MHz绝对带宽”的表述,但本领域技术人员结合脉冲无线电“短脉冲”、“低占空比”、“2GHz信道带宽”等描述,能够毫无疑义地得出其通信信道属于超宽带范畴,带宽在500MHz或更大数量级,并且相对带宽也可能很大(例如,2GHz带宽对应一个合理的中心频率,相对带宽很容易超过20%)。因此,该技术特征被直接公开。
