    • A washing machine and a method of controlling the washing machine are provided. According to the washing machine and method of controlling the washing machine, the drum is operated at a first speed so that part of laundry within the drum tumbles and another part of the laundry adheres to the drum. When an unbalance amount of the drum operating at the first speed is a first specific value or less, the speed of the drum is increased to a second speed so that all of the laundry adheres to the drum. When an unbalance amount of the drum detected during the increasing to the second speed is a second specific value or more, the rotation of the drum is decelerated. Accordingly, at a time of a dehydration cycle, stability of the washing machine and laundry balancing can be ensured.
    • 提供洗衣机和洗衣机的控制方法。 根据洗衣机和洗衣机的控制方法,滚筒以第一速度进行操作,使得滚筒内部的衣物滚动,衣物的另一部分粘附在滚筒上。 当以第一速度操作的鼓的不平衡量是第一特定值或更小时,鼓的速度增加到第二速度,使得所有衣物都粘附到滚筒。 当在增加到第二速度期间检测到的滚筒的不平衡量是第二特定值或更大时,滚筒的旋转减速。 因此,在脱水循环时,可以确保洗衣机的稳定性和衣物平衡。

    • A phase locked loop that generates an internal clock by controlling a delay time of a delay cell according to conditions of PVT, thereby improving a jitter characteristic of the internal clock. The delay cell includes a first current controller for controlling first and second currents in response to a control voltage, and a second current controller for controlling the first and second currents in response to frequency range selection signals. The phase locked loop includes a phase comparator for comparing a reference clock with a feedback clock, a control voltage generator for generating a control voltage corresponding to an output of the phase comparator, and a voltage controlled oscillator for generating an internal clock having a frequency in response to the control voltage and one or more frequency range control signals, wherein the feedback clock is generated using the internal clock.
    • 通过根据PVT的条件控制延迟单元的延迟时间来产生内部时钟的锁相环,从而提高内部时钟的抖动特性。 延迟单元包括响应于控制电压控制第一和第二电流的第一电流控制器,以及响应频率范围选择信号控制第一和第二电流的第二电流控制器。 锁相环包括用于将参考时钟与反馈时钟进行比较的相位比较器,用于产生对应于相位比较器的输出的控制电压的控制电压发生器和用于产生具有频率的内部时钟的压控振荡器 响应于控制电压和一个或多个频率范围控制信号,其中使用内部时钟产生反馈时钟。
