    • A low drop out (LDO) voltage regulator having an error amplifier, a power transistor, a first voltage division unit, a compensation control unit and a compensation bias current source is provided. The error amplifier generates a control voltage according to a first reference voltage and a feedback voltage. The power transistor generates an output voltage at a drain of the power transistor according to the control voltage. The first voltage division unit divides the output voltage to generate the feedback voltage. The compensation control unit generates a compensation control signal to the compensation bias current source according to the control voltage, the output voltage and a compensation bias, so as to make the compensation bias current source generate a compensation bias current, in which the compensation bias is inversely proportional to a supply voltage and ambient temperature.

    • A PDM system, method, and computer program product for data transfer. A method includes determining a plurality of persistent objects in a data structure to be replicated to a plurality of replication sites. The plurality of persistent objects is identified based on a transaction table entry identifying a specific scoped transaction. The method includes determining specific persistent objects of the plurality of persistent objects to be replicated to each of the plurality of replication sites based on which of the plurality of persistent objects have been updated since last being replicated to each respective replication site, without traversing the full data structure. The method includes initiating a synchronization transaction according to the specific persistent objects and replicating the specific persistent objects to at least one of the plurality of replication sites, without traversing the full data structure.
    • 用于数据传输的PDM系统,方法和计算机程序产品。 一种方法包括确定要复制到多个复制站点的数据结构中的多个持久对象。 基于识别特定作用域事务的事务表条目来识别多个持久对象。 该方法包括基于从上一次被复制到每个相应的复制站点以来多个持久对象中的哪一个已被更新而确定要复制到多个复制站点中的每一个的多个持久对象的特定持久对象,而不需要遍历整个 数据结构。 该方法包括根据特定的持久对象发起同步事务,并将特定持久对象复制到多个复制站点中的至少一个复制站点,而不用遍历完整的数据结构。
