    • There is provided a low drop-out regulator. The low drop-out regulator includes an amplifier including an odd number of operational amplifiers connected to one another in series, and an output unit including a pass transistor operated by an output from the amplifier and generating an output voltage to be applied to a load, wherein the pass transistor is an N-channel transistor, and the amplifier controls a feedback loop gain between an output terminal of one of the odd number of operational amplifiers and the output unit. The feedback loop gain may be controlled independently from the trans-conductance of the pass transistor, whereby the stable output voltage may be generated, even in the case that the load and the input voltage are changed, and the design parameter may be simplified.
    • 提供了一个低压差调节器。 低压差调节器包括一个包括串联连接的奇数运算放大器的放大器,以及一个输出单元,包括一个由放大器的输出端工作的通过晶体管,并产生一个要加到负载上的输出电压, 其中所述传输晶体管是N沟道晶体管,并且所述放大器控制所述奇数个运算放大器之一的输出端与所述输出单元之间的反馈环路增益。 反馈环路增益可以独立于传输晶体管的跨导电阻来控制,由此即使在改变负载和输入电压的情况下也可以产生稳定的输出电压,并且可以简化设计参数。

    • A switch block circuit in a field programmable gate array is provided. The switch block circuit includes a configuration memory unit including first group memories and second group memories and a switching unit including first group switching transistors and second group switching transistors. The switch block circuit further includes a selection unit for correspondingly connecting the second group memories with the second group switching transistors depending on an operation mode. The switch block is efficiently reconfigurable depending on the intended use, and configuration memories unused in a specific operation mode may be applied to other purposes.
    • 提供现场可编程门阵列中的开关块电路。 开关块电路包括配置存储单元,其包括第一组存储器和第二组存储器,以及包括第一组开关晶体管和第二组开关晶体管的开关单元。 开关块电路还包括用于根据操作模式相应地将第二组存储器与第二组开关晶体管连接的选择单元。 切换块根据预期用途有效地可重新配置,并且在特定操作模式中未使用的配置存储器可以应用于其他目的。
