**目标专利名称**:197振荡器和开始振荡的方法CN105577120B

**本次调用的模型名称**:深度专利特征比对分析模型

### 特征比对表格

技术特征描述以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**:《直接公开》对比文件图6及对应文字描述:“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...”对比文件公开了发射机中包含一个VCO,用于产生周期性的定时信号,该信号是后续生成脉冲信号的基础。这直接公开了用于“产生振荡信号”的“第一电路”(即VCO)。
**技术特征B**:《未公开》未找到对应内容。对比文件描述了VCO作为定时基准,但未描述有专门的“第二电路”向该VCO提供“第一电流”。目标专利中第二电路提供静态偏置电流以启动和维持振荡,该特定功能及电路结构在对比文件中未被公开。
**技术特征C**:《未公开》未找到对应内容。对比文件未公开任何在振荡信号初始期间提供额外“第二电流”(增强偏置电流)以缩短达到稳态时间的“第三电路”。目标专利此特征是其加速启动的核心,在对比文件中无对应描述。
**技术特征D**:《未公开》未找到对应内容。对比文件未公开任何“稳态检测器”,更未公开其基于“振荡信号的频率变化不超过1%”这一具体条件来禁止第三电路工作的功能。
**技术特征E**:《未公开》未找到对应内容。对比文件未公开用于调谐振荡电路以使信号在特定频率范围内循环的“频率校准单元”。
**技术特征F**:《未公开》未找到对应内容。对比文件未提及“静态偏置电流”和“增强偏置电流”的特定命名和区分。
**技术特征G**:《未公开》未找到对应内容。对比文件未公开由“静态直流偏置电路”响应外部使能信号来控制“第一可控电流源”施加“静态偏置电流”的具体电路架构。
**技术特征H**:《未公开》未找到对应内容。由于特征G未被公开,此连接关系亦不存在。
**技术特征I**:《未公开》未找到对应内容。对比文件未公开由“增强偏置电路”响应使能信号产生“增强偏置电流”,并通过“可控放大器”和“第二可控电流源”施加于振荡电路的具体电路架构。
**技术特征J**:《未公开》未找到对应内容。对比文件未公开频率校准单元在确定频率在范围内后,向第二电路发送禁用信号停止产生第一电流,而不向第三电路发送禁用信号的具体控制逻辑。
**技术特征K**:《未公开》未找到对应内容。对比文件未公开振荡电路内部包含“谐振电路”的具体结构描述。
**技术特征L**:《未公开》未找到对应内容。对比文件未公开振荡电路内部包含“负电阻产生器”或其与谐振电路的耦合关系。
**技术特征M**:《未公开》未找到对应内容。对比文件未公开谐振电路包含“电感器件”。
**技术特征N**:《未公开》未找到对应内容。对比文件未公开谐振电路包含与电感并联的“电容器件”。
**技术特征O**:《未公开》未找到对应内容。对比文件未公开电容器件是“可编程开关电容器组”。
**技术特征P**:《未公开》未找到对应内容。对比文件未提及任何基于“振荡信号的振幅稳定性”的“规定的稳态状况”。
**技术特征Q**:《未公开》未找到对应内容。对比文件未提及任何基于“振幅变化不超过15%”的具体稳态指标。
**技术特征R**:《未公开》未找到对应内容。对比文件未提及“频率范围等于规定的中心频率的1%”这一具体参数。
**技术特征S**:《未公开》未找到对应内容。对比文件未提及频率校准在通电、检测到环境温度变化或接收到新频率字时触发的机制。
**技术特征T**:《隐含公开》对比文件详细描述了一个入侵检测系统,该系统包含发射机和接收机(即收发机),并使用超宽带脉冲无线电信号。例如,说明书提到“The present invention includes an intrusion detection system and method that can utilize impulse radio technology...” 以及图5、图6、图7展示了通信设备框图。对比文件公开的系统利用脉冲无线电(一种超宽带技术)发射和接收信号以检测入侵者。本领域技术人员能够理解,要实现信号的发射和接收,系统必然包含收发机功能。虽然其应用场景(入侵检测雷达)与目标专利(建立通信信道)不同,但“收发机响应于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”这一技术手段在对比文件中已被隐含公开,因为其系统正是基于本地振荡器产生的信号来收发超宽带脉冲以实现设备间(发射机与接收机之间)的信息交互(即建立了通信链路,尽管用于检测)。
**技术特征U**:《隐含公开》同上。同特征T。
**技术特征V**:《隐含公开》同上。同特征T。
**技术特征W**:《隐含公开》同上。同特征T。
**技术特征X**:《隐含公开》对比文件在“Impulse radio”概述部分描述:“Impulse radio refers to a radio system based on short, low duty-cycle pulses.” 并指出脉冲持续时间小于1纳秒(如“pulse durations are less than 1 ns”)。在背景技术和详细描述中多次将其技术称为“ultra-wideband (UWB)”。对比文件明确其使用的是超宽带(UWB)脉冲无线电技术。本领域技术人员公知,亚纳秒级的脉冲必然具有极宽的带宽(通常在GHz量级)。虽然对比文件未明确写出“20%相对带宽”或“500MHz带宽”的具体数值,但其描述的“小于1ns脉冲”和“UWB技术”是本领域公认的达到或超过该数量级带宽的典型特征。因此,可以合理推断其实现的信道满足或能够满足特征X所述的超宽带信道定义。
