摘要：
In an exemplary embodiment of the present invention, a local clock buffer (LCB) fabricated in a semiconductor receives a global clock signal as input. The LCB implements a pulse width controller that is operationally coupled to the LCB and an output driver forming a ring oscillator. The output driver outputs a pulse width adjusted signal. The pulse width of the pulse width adjusted signal is adjustable by way of the pulse width controller and is related in frequency to the global clock signal. A second ring oscillator (also referred to as the nclk loop) can also be implemented to server as the global clock signal. The pulse width controller can be used to precisely adjust the pulse width of the pulse width adjusted signal. A pulse width multiplier can be implemented to allow direct observation and measurement of the pulse width of the pulse width adjusted signal.
摘要（中）：
在本发明的示例性实施例中，在半导体中制造的本地时钟缓冲器（LCB）接收全局时钟信号作为输入。 LCB实现了可操作地耦合到LCB的脉冲宽度控制器和形成环形振荡器的输出驱动器。 输出驱动器输出脉宽调整信号。 脉冲宽度调整信号的脉冲宽度可通过脉冲宽度控制器进行调节，并与频率相关于全局时钟信号。 第二个环形振荡器（也称为nclk回路）也可以实现为服务器作为全局时钟信号。 脉冲宽度控制器可用于精确调整脉宽调整信号的脉宽。 可以实现脉冲宽度乘法器，以便直接观察和测量脉冲宽度调整信号的脉冲宽度。
