    • A carbon nano-tube based photoelectric device includes a substrate and a carbon nanotube (CNT) over the substrate. The CNT comprises a first end and a second end, wherein the CNT has a CNT work function. A high work-function electrode over the substrate is in electric contact with the first end of the CNT. The high work-function electrode has a first work function higher than the CNT work function. A low work-function electrode over the substrate is in electric contact with the second end of the CNT. The low work-function electrode has a second work function lower than the CNT work function. The CNT can form a conductive channel between the high work-function electrode and the low work-function electrode. The carbon nano-tube based photoelectric device also includes a dielectric material is in contact with a side surface of the CNT and a conductive material in contact with the dielectric material.

    • A system is provided to perform non-recursive signal processing tasks using a sampled data technique and a network of switched-capacitor filters. The input analog signal is sampled in a time sequence manner at regular time intervals in order to obtain analog-valued samples. These samples are collected into data blocks and the data blocks are assembled into a set of data blocks. The successive data blocks belonging to a set of data blocks partially overlap with the first data block. The non-recursive signal processing is performed on all of the data blocks of the set substantially simultaneously, using a parallel network of switched capacitor filters, in order to produce a processed analog output signal. Each individual processing path of the parallel network of switched capacitor filters processes a specific data block of the set of data blocks. The number of parallel processing paths is the same as one plus the degree of the polynomial representing the desired or overall input/output equation characterizing the non-recursive signal processing. An implementing architecture can be simplified by factorizing the polynomial representing the input/output equation into smaller sized polynomial sub-tasks that can each be implemented by a sub-system of parallel network of switched capacitor filters of smaller complexity.
    • 提供了一种使用采样数据技术和开关电容滤波器网络执行非递归信号处理任务的系统。 为了获得模拟值样本,输入模拟信号以时间顺序方式以规则的时间间隔进行采样。 将这些样本收集到数据块中,并将数据块组装成一组数据块。 属于一组数据块的连续数据块与第一数据块部分重叠。 使用开关电容滤波器的并联网络,基本上同时对所述集合的所有数据块执行非递归信号处理,以便产生经处理的模拟输出信号。 开关电容滤波器的并联网络的每个单独处理路径处理该组数据块的特定数据块。 并行处理路径的数量与一个加上代表表征非递归信号处理的期望或总体输入/输出方程的多项式的程度相同。 可以通过将表示输入/输出方程的多项式分解为更小尺寸的多项式子任务来简化实现架构,其可以分别由较小复杂度的开关电容器滤波器的并联网络的子系统来实现。
