    • Machine readable media, methods, and computing devices are disclosed that mine a dataset using a frequent pattern array. One method of includes building a frequent pattern tree comprising a plurality of nodes to represent frequent transactions of a dataset that comprises one or more items. The method also includes transforming the frequent pattern tree to a frequent pattern array that comprises an item array and a plurality of node arrays, the item array comprising frequent transactions of the dataset and each node array to associate an item of the dataset with one or more frequent transactions of the item array. The method further includes identifying frequent transactions of the dataset based upon the frequent pattern array.

    • According to one exemplary embodiment, an amplitude compensation circuit includes a first composite programmable buffer for receiving a first input signal with a first input amplitude. The amplitude compensation circuit further includes a second composite programmable buffer for receiving a second input signal with a second input amplitude. The amplitude compensation circuit also includes a feedback circuit coupled to respective outputs of the first and second composite programmable buffers. According to this embodiment, the feedback circuit compares a first output amplitude of the first composite programmable buffer with a reference voltage and a second output amplitude of the second composite programmable buffer with the reference voltage and provides first and second control signals for adjusting the respective gains of the first and second composite programmable buffers so as to reduce respective differences between the first and second output amplitudes and the reference voltage.
    • 根据一个示例性实施例,幅度补偿电路包括用于接收具有第一输入幅度的第一输入信号的第一复合可编程缓冲器。 幅度补偿电路还包括用于接收具有第二输入幅度的第二输入信号的第二复合可编程缓冲器。 振幅补偿电路还包括耦合到第一和第二复合可编程缓冲器的相应输出的反馈电路。 根据该实施例,反馈电路将第一复合可编程缓冲器的第一输出幅度与具有参考电压的第二复合可编程缓冲器的参考电压和第二输出幅度进行比较,并提供用于调整相应增益的第一和第二控制信号 的第一和第二复合可编程缓冲器,以便减小第一和第二输出幅度与参考电压之间的差异。
