    • PURPOSE: A compensation circuit of a switch driver is provided to improve linear distortion of output power. CONSTITUTION: A dead zone sensor (120) generates sensing signals which sense a dead zone section according to the logical combination operation of a first and a second input signal having the same logical voltage level. A clock generator (130) generates a plurality of clock signals according to the logical combination operation of one signal among the sensing signals and the first and the second input signal having the same voltage level. An output power compensator (140) includes a plurality of switches switched by receiving the plurality of clock signals. The output power compensator compensates linear distortion generated in an ascending section of output power by forming a first path supplying a positive reference voltage source to an output end according to the switching operation of each switch. The output power compensator compensates the linear distortion generated in a descending section of the output power by forming a second path sinking the output power on the output end to a negative reference voltage source side.

    • 目的:提供开关驱动器的补偿电路,以改善输出功率的线性失真。 构成:死区传感器(120)根据具有相同逻辑电压电平的第一和第二输入信号的逻辑组合操作产生感测死区部分的感测信号。 时钟发生器(130)根据感测信号中的一个信号的逻辑组合操作和具有相同电压电平的第一和第二输入信号产生多个时钟信号。 输出功率补偿器(140)包括通过接收多个时钟信号而切换的多个开关。 输出功率补偿器通过根据每个开关的切换操作形成向输出端提供正参考电压源的第一路径来补偿在输出功率的上升部分中产生的线性失真。 输出功率补偿器通过形成将输出端上的输出功率吸收到负参考电压源侧的第二路径来补偿在输出功率的下降部分中产生的线性失真。 (附图标记)(120)死区传感器; (130)时钟发生器; (140)输出功率补偿器; (150)过滤器; (50)开关驱动器

    • PURPOSE: A surface treating method of ceramic particles is provided to improve the solvent wettability and dispersibility of ceramic particles by treating the surfaces of the ceramic particles with an ionic polymer. CONSTITUTION: The surface property of ceramic particles, of which surfaces are treated with an ionic polymer, is possibly controlled. The ionic polymer is an anionic polymer and is one of poly (acrylic acid), poly (sodium 4-styrene sulfonate), poly (vinyl sulfonic acid), poly (sodium salt), and poly (amino acid). The ionic polymer is a cationic polymer and is one of poly (diallydimethylammonium chloride), poly (allylamine hydrochloride), poly (4-vinyl benzyl trimethyl ammonium chloride), and poly (ethylene imine). A surface treating method of ceramic particles includes the steps of: adjusting the pH of a solution containing ceramic particles using a predetermined solution; and controlling the surface property of the ceramic particles using an ionic polymer.
