    摘要: An easy LSB tuning method is proposed for a digitally controlled DC-DC converter to increase the DC gain of the digitally controlled DC-DC converter under conditions of no-limit-cycle and a finite bit number to reduce steady-state error of the digitally controlled DC-DC converter. The LSB of one or more of the coefficients in the denominator of the discrete-time domain transfer function of the digital compensator in the digitally controlled DC-DC converter is so tuned that the sum of all coefficients in the denominator of the discrete-time domain transfer function becomes zero. Therefore, the influence of round-off effect on the coefficients of the digital compensator is mitigated.

    摘要: A multi-phase buck converter has a digital compensator to select a set of compensation coefficients depending on the operating phase number of the multi-phase buck converter, or including different compensators for each operation phase number to improve the loop gain bandwidth, transient response and stability of the multi-phase buck converter. The multi-phase buck converter operates with more phase circuits for higher loading and operates with fewer phase circuits for lower loading. The compensation varies with the number of the operated phase circuits so to be adaptive to the operation condition with an optimized control-to-output voltage transfer function.

    摘要: An exemplary liquid crystal display (LCD) (200) includes a first substrate (210); a second substrate (230) opposite to the first substrate; a liquid crystal layer (250) sandwiched between the first substrate and the second substrate; a first common electrode (211), a first insulating layer (212), and pixel electrodes provided at an inner surface of the first substrate in that order; and second common electrodes (231) and floating electrodes (233) provided at the second substrate. The first common electrode and the pixel electrodes, and the second common electrodes and the floating electrodes, respectively produce two electric fields in the liquid crystal layer corresponding to each other. A combined electric field strength is uniformly distributed in the liquid crystal layer, so that all the liquid crystal molecules can be sufficiently twisted. Thus a viewing angle, a degree of chroma, and a transmission ratio of the LCD are improved.

    摘要: An xDSL (Digital Subscriber Line) modem (160) includes a setting module (168), a detection module (164), and a distinguishing module (166). The setting module pre-sets a threshold value, and adjusts the threshold value according to noise types. The detection-module captures connection parameters of the xDSL modem and the central office (CO) (120), and computes a judging value. The distinguish module distinguishes noise types according to the judging value, and determines whether the connection is maintained or disconnected. A method for stabilizing connection between an xDSL modem and a CO is also provided.

    摘要: An apparatus for homogeneously distributing lights includes a light guide plate, an incidence microstructure and an emergence microstructure. The incidence microstructure is arranged on a surface of the light guide plate and opposite to a light source. The emergence microstructure is arranged on a surface of the light guide plate opposite to the incidence microstructure. The lights emitted by the light source pass through said apparatus thereby being homogenously distributed. Thus the manufacture costs are lowered, and the light source utilization ratio is increased.
