    • In view of achieving a cost reduction of an antenna switch, a technique is provided which can reduce harmonic distortion generated in the antenna switch as much as possible in particular even when the antenna switch is comprised of a field effect transistor formed over a silicon substrate.Each of a TX series transistor, an RX series transistor, and an RX shunt transistor is comprised of a low voltage MISFET, while a TX shunt transistor is comprised of a high voltage MISFET. Thus, by reducing the number of serial connections of the high voltage MISFETs constituting the TX shunt transistor, the nonuniformity of the voltage amplitudes applied to the respective serially-coupled high voltage MISFETs is suppressed. As a result, the generation of high-order harmonics can be suppressed.
    • 考虑到实现天线开关的成本降低,提供了即使当天线开关由在硅衬底上形成的场效应晶体管构成时,也可以尽可能地减少天线开关中产生的谐波失真的技术。 TX系列晶体管,RX系列晶体管和RX分流晶体管中的每一个由低电压MISFET组成,而TX并联晶体管由高电压MISFET组成。 因此,通过减少构成TX并联晶体管的高电压MISFET的串联连接数,可抑制施加到各串联耦合的高电压MISFET的电压幅度的不均匀性。 结果,可以抑制高次谐波的产生。

    • A recording/reproducing apparatus is provided that is used by a plurality of users and simplifies file management in a storage medium in which many content items are stored. With the use of the recording/reproducing apparatus (1), when recording and reproducing contents on and from an optical disk D, recording and reproducing history information is recorded and updated for each content item and for each user who has recorded the content, will reproduce the content, and is reproducing the content. The recording and reproducing history information includes information, for example, indicative of whether or not each content item has been reproduced, and a reproducing restriction set on each content item. Displaying such information realizes simple file management. For example, it is possible to fetch contents that have not been commonly reproduced among plural users, or delete contents that have been reproduced by all users, both quickly and reliably.
    • 提供了一种由多个用户使用的记录/再现装置,并简化了存储许多内容项的存储介质中的文件管理。 利用记录/再现装置(1),当在光盘D上记录和再现内容时,对于每个内容项目以及对于已经记录了内容的每个用户来说,记录和更新记录和再现历史信息,将会 再现内容,并且正在再现内容。 记录和再现历史信息包括例如指示每个内容项是否已经被再现的信息,以及对每个内容项设置的再现限制。 显示这样的信息实现简单的文件管理。 例如,可以在多个用户之间获取未被普遍再现的内容,或者可以快速且可靠地删除所有用户再现的内容。
