**对比文件名称:** EP1981168A1_Description_20260304_2025

**本次调用的模型名称:** 专利创造性评估模型

根据对目标专利说明书和权利要求、以及对比文件EP1981168A1说明书的详细分析,现创建特征比对表格如下:

### 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
**特征A:所述装置包括:第一电路,用以产生振荡信号** <br>《直接公开》[0007] “The apparatus comprises a first circuit to generate an oscillating signal” <br>(装置包括第一电路,用以产生振荡信号)<br>[0027] “...the inventive device or apparatus ... comprises a first circuit to generate an oscillating signal” <br>(……创新装置……包括第一电路以产生振荡信号)对比文件明确公开了装置包括用于产生振荡信号的第一电路,其作用与目标专利中完全相同。本领域技术人员能够毫无疑义地得出该技术方案。因此,特征A被直接公开。
**特征B:第二电路,用以向所述第一电路提供第一电流** <br>《直接公开》[0007] “a second circuit to supply a first current to the first circuit” <br>(第二电路,用以向第一电路提供第一电流)对比文件明确公开了第二电路及其功能是向第一电路提供第一电流,其作用与目标专利中相同。因此,特征B被直接公开。
**特征C:第三电路,用以仅在所述振荡信号的初始期间向所述第一电路提供第二电流,其中,所述第一电流和所述第二电流适于减少所述振荡信号达到规定的稳态状况的时间长度,所述规定的稳态状况包括所述振荡信号的频率稳定性** <br>《隐含公开》[0011] “the apparatus may further comprise a steady-state detector adapted to disable the third circuit from supplying the second current to the first circuit in response to detecting the defined steady-state condition of the oscillating signal. Thus, the third circuit may only be used upon start up to quickly achieve the defined steady-state condition of the oscillating signal.” <br>(该装置还可以包括稳态检测器,所述稳态检测器适于响应于检测到所述振荡信号的规定的稳态状况而禁止所述第三电路向所述第一电路提供所述第二电流。因此,第三电路可仅在启动时用于快速实现所述振荡信号的规定的稳态状况。)<br>[0040] “The defined steady-state condition may also specify a frequency stability of the oscillating signal of not varying more than one (1) percent.” <br>(所述规定的稳态状况还可以将振荡信号的频率稳定性指定为变化不超过1%。)1. **关于“仅在初始期间提供”**:对比文件[0011]明确说明第三电路“仅在启动时使用”,并将在检测到稳态后由稳态检测器禁用。这必然意味着第三电路是在振荡信号达到稳态之前(即初始启动期间)提供电流,与本特征“仅在初始期间”的限定相符。<br>2. **关于“减少达到稳态的时间”**:[0007]已明确第一和第二电流用于减少达到稳态的时间,且[0011]指出第三电路用于“快速实现”稳态。<br>3. **关于“规定的稳态状况包括频率稳定性”**:[0040]明确将频率稳定性(变化不超过1%)规定为稳态状况的一种具体技术要求。<br>综上,对比文件已部分公开(电流作用、启动时使用、稳态包括频率稳定),本领域技术人员结合这些内容,能够合理推断出“第三电路在初始期间提供第二电流以减少达到包含频率稳定性要求的稳态状况的时间”这一完整技术方案。因此,特征C被隐含公开。
**特征D:稳态检测器,所述稳态检测器适于响应于检测到所述振荡信号的频率变化不超过1%而禁止所述第三电路向所述第一电路提供所述第二电流** <br>《隐含公开》[0011] “the apparatus may further comprise a steady-state detector adapted to disable the third circuit from supplying the second current to the first circuit in response to detecting the defined steady-state condition of the oscillating signal.” <br>(该装置还可以包括稳态检测器,所述稳态检测器适于响应于检测到所述振荡信号的规定的稳态状况而禁止所述第三电路向所述第一电路提供所述第二电流。)<br>[0040] “The defined steady-state condition may also specify a frequency stability of the oscillating signal of not varying more than one (1) percent.” <br>(所述规定的稳态状况还可以将振荡信号的频率稳定性指定为变化不超过1%。)对比文件明确公开了稳态检测器及其功能(检测稳态并禁用第三电路),也明确了稳态条件可以具体为“频率变化不超过1%”。虽然[0011]和[0040]的表述未在同一个句子中直接关联,但本领域技术人员阅读说明书整体后,能够毫无困难地理解:当将稳态条件具体设定为“频率变化不超过1%”时,稳态检测器的工作逻辑就是检测到此条件满足后禁用第三电路。这是一种直接的、合理的组合应用。因此,特征D被隐含公开。
**特征E:及频率校准单元,所述频率校准单元适于调谐所述第一电路,以使得所述振荡信号在频率范围之内循环,** <br>《直接公开》[0012] “the apparatus may further comprise a frequency calibration unit adapted to tune the first circuit so that the oscillating signal cycles within a defined frequency range.” <br>(该装置还可以包括频率校准单元,所述频率校准单元适于调谐所述第一电路,以使得所述振荡信号在规定的频率范围之内循环。)<br>[0030] “The frequency calibration unit 158 ... generates a frequency tuning word that tunes the oscillating circuit 160 so that the frequency of the oscillating signal is within the requirement...” <br>(频率校准单元158……产生频率调谐字,其调谐振荡电路160,以使得振荡信号的频率在要求之内……)对比文件明确公开了频率校准单元及其功能是调谐第一电路(振荡电路),使振荡信号在规定的频率范围内循环。其作用与目标专利中完全相同。因此,特征E被直接公开。

In response to receiving an enable signal, the quiescent DC bias circuit 402 controls the quiescent bias current that is applied to the oscillating circuit 412 by the first controllable current source 404.” <br>(装置400还包括直流(DC)电源410、第一可控电流源404和静态DC偏置电路402。……响应于接收到使能信号,静态DC偏置电路402控制由第一可控电流源404施加到振荡电路412的静态偏置电流。)对比文件图4及对应描述[0044]明确公开了“静态DC偏置电路”(quiescent DC bias circuit 402),其功能是响应于使能信号,控制“第一可控电流源”(first controllable current source 404)向振荡电路(即第一电路)提供静态偏置电流。该结构、部件及其交互关系与特征G的描述完全一致。因此,特征G被直接公开。
**特征H:其中,所述第一可控电流源连接到用以产生所述振荡信号的所述第一电路,** <br>《直接公开》[0044] “... the quiescent bias current that is applied to the oscillating circuit 412 by the first controllable current source 404.” <br>(……由第一可控电流源404施加到振荡电路412的静态偏置电流。)由[0044]的引用可知,第一可控电流源404的输出施加到振荡电路412,即两者是连接的。这直接公开了第一可控电流源连接到第一电路(振荡电路)。因此,特征H被直接公开。

**特征J:,并且其中,响应于确定所述振荡信号的频率在所述频率范围之内,所述频率校准单元向所述第二电路发送禁用信号来停止产生所述第一电流而不向所述第三电路发送所述禁用信号。** <br>《直接公开》[0036] “If, in operation 212, the frequency calibration unit 158 determines that the measured frequency of the oscillating signal is within the defined range, the frequency calibration unit 158 stores the frequency tuning word (block 218). The frequency calibration unit 158 then sends a disable oscillator signal to the circuit 152 to cease generating the first current so as to disable the oscillating circuit (block 220). Note, that the frequency calibration unit 158 need not send the disable oscillator signal to the circuit 154 because the output steady-state detector 156 may have already disabled the circuit 154 after detecting the defined steady-state condition of the oscillating signal.” <br>(如果在操作212中,频率校准单元158确定振荡信号的测量频率在规定范围之内,频率校准单元158就存储该频率调谐字(块218)。频率校准单元158随后向电路152发送禁用振荡器信号来停止产生第一电流,以便禁用振荡电路(块220)。注意,频率校准单元158不必向电路154发送禁用振荡器信号,因为输出稳态检测器156可以在检测到振荡信号的规定的稳态状况之后已经禁用了电路154。)对比文件方法200的流程图描述(对应图2)明确公开了:频率校准单元在确定频率在规定范围内后,向第二电路(电路152)发送禁用信号以停止第一电流;同时明确指出不需要向第三电路(电路154)发送该禁用信号,因为稳态检测器已将其禁用。该操作逻辑与特征J的描述完全吻合。因此,特征J被直接公开。
**特征K:其中,所述第一电路包括:谐振电路** <br>《直接公开》[0010] “the first circuit of the apparatus may comprise a tank circuit coupled to a negative resistance generator.” <br>(所述装置的第一电路可以包括耦合到负电阻产生器的谐振电路(tank circuit)。)对比文件明确公开了第一电路包括谐振电路(tank circuit)。因此,特征K被直接公开。

**特征O:其中,所述电容器件包括可编程开关电容器组。** <br>《直接公开》[0010] “The capacitive element may comprise a programmable switched capacitor bank for tuning the frequency of the oscillating signal.” <br>(电容元件可以包括可编程开关电容器组,用于调谐振荡信号的频率。)<br>[0043] “... a switched capacitor bank 416 ...” <br>(……开关电容器组416……)对比文件明确公开了电容元件包括可编程开关电容器组(programmable switched capacitor bank)。因此,特征O被直接公开。

**特征Q:其中,所述规定的稳态状况是基于所述振荡信号的振幅变化不超过15%。** <br>《直接公开》[0040] “For example, the defined steady-state condition may specify an amplitude stability of the oscillating signal of not varying more than 15 percent.” <br>(例如,所述规定的稳态状况可以将振荡信号的振幅稳定性指定为变化不超过15%。)对比文件明确给出了“振幅变化不超过15%”这一具体的稳态状况技术指标。因此,特征Q被直接公开。
**特征R:其中,所述频率范围等于规定的中心频率的1%。** <br>《隐含公开》[0033] “For example, the specified frequency range may be as large as one percent of a defined center frequency.” <br>(例如,所述指定的频率范围可以达到规定的中心频率的1%。)对比文件给出了频率范围“可以达到”(as large as)中心频率1%的示例。虽然“可以达到”与“等于”在字面严格意义上略有差异,但本领域技术人员在具体实施该技术方案时,为了满足“规定频率范围”的要求,完全可能且合理地将其设定为“等于中心频率的1%”。这是一种常规的、直接的设计选择,属于等同替换或具体应用。因此,特征R被隐含公开。
**特征S:其中,所述频率校准单元在所述装置通电时、在检测到高于规定阈值的环境温度变化时、或在接收到用于所述第一电路的新的频率字时,调谐所述第一电路。** <br>《直接公开》[0012] “The frequency calibration unit may be adapted to calibrate or tune the first circuit upon power up, upon detecting an ambient temperature change above a defined threshold, and/or upon receiving a new frequency specification for the oscillating signal.” <br>(频率校准单元可以适于在通电时、在检测到高于规定阈值的环境温度变化时、和/或在接收到振荡信号的新的频率技术要求时,校准或调谐第一电路。)<br>[0030] “The frequency calibration unit 158 may calibrate the frequency of the oscillating signal upon power up, upon receiving a new frequency input word, and/or upon detecting a change in ambient temperature that exceeds a defined threshold.” <br>(频率校准单元158可以在通电时、在接收到新的频率输入字时、和/或在检测到超过规定阈值的环境温度变化时,校准振荡信号的频率。)对比文件明确且完整地公开了频率校准单元进行调谐的三个触发条件:通电、环境温度变化超阈值、收到新的频率输入字。其内容与特征S完全一致。因此,特征S被直接公开。
**特征T/U/V/W:还包括收发机,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。** <br>《隐含公开》[0013] “one or more apparatuses may be used as local oscillators (LOs) in communication systems and devices to up convert and down convert signals. For example, the apparatus may be used to establish one or more ultra-wide band (UWB) channels for communicating with other devices...” <br>(一个或多个装置可以用作通信系统和设备中的本地振荡器(LO),以便对信号进行上变频和下变频。例如,所述装置可以用于建立一条或多条超宽带(UWB)信道,以便与其它设备通信……)<br>[0047] “The pulse modulator 516 is coupled to the receiver LO 510 to enable the receiver LO ... in order to establish a receiving communication channel (e.g., an ultra-wide band (UWB) communication channel) ...
