    • The present invention relates to a combination RF tuner capable of receiving signals from the FM radio band and from the TV band. Prior art combination tuners had to compromise in quality resulting in combination tuners that neither exhibited high-end FM­nor TV- signal reception behavior. A combination RF tuner capable of optimal receiving an FM-radio signal type and a TV signal type, comprising a switch-able tuned input filter (440), is proposed. One response of the input filter (440) provides a sufficient big bandwidth for enabling reception of the TV-signal type. The input filter (440) of the invention can be switched, providing a second response that has a smaller bandwidth for enabling reception of the FM-radio signal type. The second response can be realized by substantially bypassing an 10 inductive element (450) (e.g., comprising a inductor, L21, in series with a damping resistor, R3) of the input filter (440).

    • A fully integrated single-loop frequency synthesizer, which can serve as a local oscillator for a broadband tuner, is disclosed, thus allowing the creation of a single-chip solution for broadband applications. The tank circuits are integrated into the tuner chip through the combination of a phase-locked loop and multiple on-chip VCOs comprising narrow-tuning range varactors. Drift in the VCOs caused by heat is overcome by designing the VCOs to overlap each other. Initial tolerance problems associated with the VCOs are overcome by the use of a calibration method. The calibration of the VCOs is accomplished by utilizing the lock detect output of the phase-locked loop and a binary search algorithm. The edges of each VCO are determined with this calibration method, thereby enabling VCO selection based on the desired channel. A sufficient number of VCOs are provided such that whatever the initial tolerance shift, the full broadband spectrum can still be covered after calibration. Additionally, the problem of coupling between the local oscillator signal and the incoming radio frequency signal is mediated by the use of a programmable 2/4 divider. This 2/4 divider also provides additional flexibility in choosing the number of VCOs to put on the chip and which VCO to use in a particular implementation.
    • 公开了一种完全集成的单回路频率合成器,可以用作宽带调谐器的本地振荡器,从而允许为宽带应用创建单芯片解决方案。 通过锁相环和包括窄调范围变容二极管的多个片上VCO的组合,将谐振电路集成到调谐器芯片中。 通过设计VCO彼此重叠来克服由热引起的VCO中的漂移。 通过使用校准方法来克服与VCO相关的初始容差问题。 VCO的校准通过利用锁相环的锁定检测输出和二进制搜索算法来实现。 使用该校准方法确定每个VCO的边缘,从而基于期望的信道实现VCO选择。 提供足够数量的VCO,使得无论初始容限偏移如何,校准后仍然可以覆盖全宽带频谱。 此外,本地振荡器信号和输入射频信号之间的耦合问题是通过使用可编程2/4分频器进行调节的。 该2/4分频器还提供了选择放置在芯片上的VCO数量以及哪个VCO在特定实现中使用的额外灵活性。
